Maingear's New ‘Desktop Replacement' Ultima 18 Gaming Laptop Is No Joke
Ultima 18
I recently watched Victor Lucas' review of the MSI Titan 18 HX AI, an $8,000 gaming laptop for people with deep pockets and a penchant for financial self-destruction, I'm assuming. The machine features an 18-inch 4K display, as well as a mobile GeForce RTX 5090, an Intel Core Ultra 9 285HX, and is outfitted with enough hardware bells and whistles to earn it 'desktop replacement' status, as well as a price that could make a grown man cry (shoutout to My Retro Life for this gem).
Well, it's rather fitting that premium system integrator Maingear is now getting in on the portable powerhouse action with a potential rival product they're dubbing the Ultima 18--not that Ultima--which starts at a much more reasonable $3,599, although the price will naturally balloon depending on which specific components you want installed, or if you choose to pay for a 'boost,' which doubles the RAM and SSD capacity for non-customized pre-configurations.
Speaking of, here is a rough spec run-down:
Ultima 18
Back in 2024, I reviewed Maingear's comparable ML-17 gaming laptop and thought it was excellent. Admittedly, with a screen measuring 17.3 inches, the ML-17's display is notably smaller than the new Ultima 18, and the ML-17 is also much lighter, coming in at 7.25 pounds, whereas the Ultima 18 purportedly weighs over a pound more. Like the ML-17, Maingear is touting the Ultima 18 as something you can easily slip into your backpack, but your backpack better be, uh, big? Squats are a health inclusion in any strength-training routine, by the way.
Sure, the Ultima 18 is a heavier beast, but on top of the larger display, you're additionally getting the latest top-tier internals, notably a 50-series mobile GPU and a cutting-edge Intel Core Ultra 9 275HX CPU. That's on top of whatever amount of RAM you decide to include, and I also dig the option for so many extra M.2 NVMe SSDs. There's even a valuable PCIe Gen 5 slot for one of those newfangled faster drives.
The battery here is pretty standard fare for these types of laptops, and you likely won't be getting more than two-ish hours on a single charge while playing games on relatively demanding settings, at least judging from my experience with the ML-17. However, I'm sure most people will be keeping this kind of device plugged in when gaming--hotel room Cyberpunk 2077 for the win. Honestly, I wouldn't plug this laptop into an outlet on an airplane, simply for fear of throttling the damn engines. A new 330W charger is packed in with the Ultima 18, and it does support USB-C charging for power emergencies.
Ultima 18
I'm very interested to see how loud this thing gets when firing on all cylinders, and how toasty the metal chassis feels during intense gaming sessions, but 18 inches of 4K display real estate is undeniably compelling. A mobile 5090 doesn't sound too shabby either, and Maingear's signature understated design looks to be present.
If the company's impressive track record is any indication, I wouldn't be surprised if they have another performance and aesthetic winner on their hands, but we'll know for sure once reviews begin popping up. Will this replace your (or my) desktop, I wonder? At least it's not $8,000. For that cost, a laptop better replace my existential anxiety with permanent, unbridled joy. That's how happiness works, yeah? You can buy it?
The Ultima 18 is available to purchase today on Maingear's website.

PCIe 7.0 is coming, but not soon, and not for you
The PCIe 7.0 specification has now been released, while many of us are still waiting for PCIe 6.0 to materialize in consumer products. The PCI Special Interest Group (PCI-SIG) announced on Wednesday that PCIe 7.0 is now available to members of its organization, delivering a theoretical maximum bandwidth speed of 512GB per second in both directions, across a x16 connection. 'PCIe technology has served as the high-bandwidth, low-latency IO interconnect of choice for over two decades and we are pleased to announce the release of the PCIe 7.0 specification, which continues our long-standing tradition of doubling the IO bandwidth every three years,' PCI-SIG President Al Yanes said in the announcement. 'As artificial intelligence applications continue to scale rapidly, the next generation of PCIe technology meets the bandwidth demands of data-intensive markets deploying AI, including hyperscale data centers, high performance computing (HPC), automotive, and military/aerospace.' You may have noticed that consumer computing devices weren't included in that statement — the specification is targeting data-driven applications like cloud and quantum computing datacenters for now, and will take some time to even appear in those markets. PCI-SIG says that PCIe 7.0 will be backward compatible with previous PCI Express versions, but there's no mention of plans to bring it to everyday desktop SSDs or GPUs any time soon. That shouldn't be surprising, given the PCIe 5.0 spec that launched in 2019 only started trickling into consumer hardware two years ago, and is still fairly uncommon. Image: PCI-SIG

Cynthia Lummis Proposes Artificial Intelligence Bill, Requiring AI Firms to Disclose Technicals
Senator Cynthia Lummis (R-WY) has introduced the Responsible Innovation and Safe Expertise (RISE) Act of 2025, a legislative proposal designed to clarify liability frameworks for artificial intelligence (AI) used by professionals. The bill could bring transparency from AI developers – stoping short of requiring models to be open source. In a press release, Lummis said the RISE Act would mean that professionals, such as physicians, attorneys, engineers, and financial advisors, remain legally responsible for the advice they provide, even when it is informed by AI systems. At the time, AI developers who create the systems can only shield themselves from civil liability when things go awry if they publicly release model cards. The proposed bill defines model cards as detailed technical documents that disclose an AI system's training data sources, intended use cases, performance metrics, known limitations, and potential failure modes. All this is intended to help help professionals assess whether the tool is appropriate for their work. "Wyoming values both innovation and accountability; the RISE Act creates predictable standards that encourage safer AI development while preserving professional autonomy,' Lummis said in a press release. 'This legislation doesn't create blanket immunity for AI," Lummis continued. However, the immunity granted under this Act has clear boundaries. The legislation excludes protection for developers in instances of recklessness, willful misconduct, fraud, knowing misrepresentation, or when actions fall outside the defined scope of professional usage. Additionally, developers face a duty of ongoing accountability under the RISE Act. AI documentation and specifications must be updated within 30 days of deploying new versions or discovering significant failure modes, reinforcing continuous transparency obligations. The RISE Act, as it's written now, stops short of mandating that AI models become fully open source. Developers can withhold proprietary information, but only if the redacted material isn't related to safety, and each omission is accompanied by a written justification explaining the trade secret exemption. In a prior interview with CoinDesk, Simon Kim, the CEO of Hashed, one of Korea's leading VC funds, spoke about the danger of centralized, closed-source AI that's effectively a black box. "OpenAI is not open, and it is controlled by very few people, so it's quite dangerous. Making this type of [closed source] foundational model is similar to making a 'god', but we don't know how it works," Kim said at the time.

Robotaxi wars: How Waymo got the edge on the competition, and Tesla (so far)
'We are being super paranoid about safety." That's what Tesla CEO Elon Musk said after revealing the company's robotaxi test would start on June 22, later than expected, adding that the date could 'shift' beyond that. Meanwhile, betting site Polymarket lists only a 30% chance that Tesla (TSLA) launches the service before July, highlighting Musk's rosy predictions on self-driving that have been constantly pushed back. While Tesla is on the verge of starting a new chapter for the company, Alphabet's (GOOG) Waymo has been quietly racking up mile after mile, trip after trip, providing actual paid robotaxi rides to customers in San Francisco, Phoenix, Los Angeles, and Austin — where Tesla's test will begin. At stake is a huge opportunity for companies like Waymo, Tesla, and others. Goldman analyst Mark Delaney estimates the market for traditional ride-hailing in the US is worth approximately $58 billion currently, but could be worth more than $330 billion by 2030, with robotaxi-type services pushing the industry forward and reducing costs by — among other factors —not requiring a human driver. Waymo has an early lead, and it seems a big one. Rivals like Argo AI and GM-backed Cruise are gone, leaving only smaller players like Zoox (backed by Amazon), China's Pony AI (PONY) and WeRide (WRD), and of course Tesla. Waymo (before it was even called that) started off as an in-house startup as part of Google's X initiative way back in 2009. After some testing and securing of permits, the project officially became Waymo in 2016, and it started testing its Pacifica hybrid vans kitted out with cameras, LIDAR laser sensors, and radar. In 2018 Waymo and Jaguar paired up, using the British automaker's I-Pace EV for its testing; these are the vehicles most users are accustomed to seeing. Waymo's combination of vision, radar, and LIDAR, which the company calls its 'multimodal' approach, has the company claiming it has the best, and safest, robotaxi solution. Since 2020, anyone in a service area can download the Waymo app and hail a fully autonomous car. Waymo says it has the most robotaxi miles driven and that the company performs around 250,000 trips a week. A Waymo spokesperson said that the company has not yet seen a vision-only system that can achieve the levels of safety its current system has achieved, asserting that multiple sensors with overlapping fields of view are the best solution. Experts tend to agree. 'Waymo is undoubtedly the leader in autonomous driving technology, with their self-driving software (SDS) being widely regarded as best in class,' said University of San Francisco engineering professor William Riggs, an expert in autonomous technology. 'They have been around the longest, had patient capital and have the most miles on the road proving that self-driving tech works.' Riggs believes Waymo's software strategy combined with its diversified sensor suite, along with its manufacturer partnerships such as Chrysler, Hyundai, Zeekr, and Toyota, allowed Waymo to maintain a strong presence in the market and adapt to different vehicle platforms. Autonomous expert Katie Driggs-Campbell of University of Illinois' Grainger College of Engineering agrees. 'Initially, I believe their strength came from the computer vision/learning and compute expertise from Google,' Driggs-Campbell said, noting that Waymo has now 'blended real-world experience, recorded data, and simulation [generated] data to form a reliable system.' Waymo also touts its safety record, as well as how open it's been with data. 'We have an incredibly rigorous safety framework in place, and our safety record speaks for itself,' Waymo's spokesperson said, adding that the company has been voluntarily sharing safety performance data with the public, which goes beyond regulatory requirements. Waymo's approach could not be more different from Tesla's, and that has contributed to the dominant lead it sees currently. Tesla did not immediately respond to Yahoo Finance when seeking comment. But per Musk biographer Walter Isaacson, Musk was enamored with Tesla's vision-only, neural network-powered self-driving system when it was presented to him. He deemed it superior to Tesla's prior system, which ran on millions of lines of code using a rules-based system fed by data coming from radar and LIDAR sensors. Tesla's current FSD (full self-driving) and robotaxi software use only a vision-based system powered by a neural network 'brain' that is constantly training itself using videos collected by millions of Tesla vehicles. (And as opposed to Waymo, Tesla has reportedly asked the city of Austin to block release of safety records related to its robotaxi launch.) While Waymo holds a big early lead, what could stop the pioneer from growing more could be its operations and manufacturing ability. Riggs believes building vehicles at scale remains a significant hurdle for Waymo. 'Currently, they operate between 700 and 1,000 vehicles in their major markets and are producing roughly 1,500 vehicles annually. This relatively modest production volume could become a bottleneck for scaling their operations further,' he said. The other challenge for startups like Waymo in general versus Tesla is that their costs per vehicle are higher. Waymo's self-driving tech and sensors reportedly cost $100,000 plus the cost of the vehicle itself (for example, the Jaguar I-Pace retails for $73,875 in the US). While some of those costs have come down, scaling to new cities and providing enough vehicles to take on Uber, for example, will require more than the 1,500 vehicles currently produced a year. Tesla, meanwhile, has the ability to produce 2 million or more EVs a year, which include the hardware necessary for its FSD and robotaxi software. Tesla also has millions of vehicles on the road that could be converted for robotaxi use, though that would require the company's Hardware 4 autopilot software, which only started rolling out in early 2023. 'AI runs off of data. Waymo is trying to close that data gap with more sensors per vehicle; Tesla is looking to win with more vehicles with targeted data specific to their vision-only approach,' said Ken Johnston, vice president of data and analytics at tech consulting firm Envorso and former exec at Ford and Microsoft. 'Companies like BYD and Tesla also cannot be ruled out, as they continue to innovate and expand their capabilities in this space,' Riggs added. Xiaomi is also testing autonomous driving in China, but the company has suffered from safety issues in early trials. Johnson is bullish on Tesla's robotaxi offering, but the company faces a big challenge in surviving its safety test. Uber's self-driving unit and GM's Cruise could not overcome high-profile accidents. Testing the service without any accidents in a semi-urban environment is not easy. And unlike Waymo, Tesla is under federal investigation for its autonomous software. It also still needs to provide NHTSA with answers to how it plans to roll out its robotaxi program. Meanwhile, Waymo is plugging along, adding more cities to its list of current operations, with Atlanta, Miami, and Washington, D.C., coming online in 2026. Being backed by Alphabet helps too, giving Waymo capital runway for growth, investment, and long-term community outreach. Waymo's technological lead and strong backing from Alphabet clearly have the service in pole position. But this race is far from over. Pras Subramanian is the lead auto reporter for Yahoo Finance.
