WWDC 2025: Apple is still behind on AI, but does it matter?
WWDC 2025: Apple is still behind on AI, but does it matter? Show Caption Hide Caption How to use AI rewriting tools Artificial Intelligence can instantly proofread your writing and make suggestions to tweak the tone of a message, paper or presentation. Problem Solved Going into this year's Worldwide Developer Conference (WWDC) event, there's been a lot of speculation about what Apple would, or wouldn't, say about Apple Intelligence and updates to its Siri personal assistant. After all, it was at the same event last year that Apple first unveiled Apple Intelligence with great fanfare, so interest has been riding high. Given how disappointing the reality of those features have been compared to the impressive demos and grandiose vision that Apple shared last year, the anticipation has been even greater. Alas, while the company did make a number of glitzy announcements about design and naming and offered up some specific new Apple Intelligence-powered features, there wasn't much steak behind the sizzle on the AI front. In fact, Siri was only mentioned once, and it was to basically say more will be coming later this year. Making iPad more functional The most important announcement from the show had nothing to do with AI, but with bringing a true computer-like user interface to the iPad. The next version of iPadOS will finally bring a true multi-application, multi-windowing environment to Apple's tablet as well as a file system, nested folders and all the other things you expect on a PC. In essence, it will make the iPad Apple's first real touch-based computer, something that a lot of people will undoubtedly be excited about. A new interface On the design front, the company spent a great deal of time showing off their new Liquid Glass user interface design − inspired by the VisionPro OS − and made it clear it will become the consistent new look across all of Apple's devices. They also announced year-based naming conventions for all their operating systems, including iOS, MacOS, iPadOS, etc. They will all be tagged as version 26, so named since they're expected to all launch later this fall and be the standard for most of 2026. Smarter intelligence On the AI front, despite Apple pulling back noticeably from their AI-first messaging of last year, they did still announce several new features that will leverage AI capabilities. The new Visual Intelligence features for iOS and iPadOS, for example, will allow you to easily do visual searches of both objects around you and the content on your screen via screenshots. In essence, it's an easier way to do image-based searches, which is a handy capability that not everyone takes advantage of. In a hint of things to come, you can also use it to do things like take a screenshot of an event announcement and have it automatically added to your calendar. For app developers Apple also announced the ability to access the small on-device AI models that Apple has built into iOS and iPadOS via a new extension to the operating system. Over time, that should lead to some interesting new AI-powered features in apps that choose to leverage these capabilities, but it's still far from an overall AI-driven experience. AI still waiting for its moment In spite of the disappointment that AI enthusiasts may feel about this lack of news from WWDC, however, it's certainly worth pondering whether it's really going to matter to most people − at least right now. Yes, there are some amazing AI-powered capabilities on Android via Google's Gemini, on Windows thanks to its partnership with OpenAI, and across all the hot new AI tools, such as Perplexity, Claude and many others. And yes, it's a bummer that the more advanced capabilities − such as digital agents and personalized digital assistants − aren't yet available on Apple devices. In truth, however, most people still haven't really started using most of these tools on a regular basis. Oh sure, there are definitely AI diehards who are using these capabilities all the time and who sing their praises on a regular basis. Normal folks who just want to use their phones, computers, tablets and other devices to do the kind of stuff they've been doing − communicating, researching, planning, gaming, watching entertainment, etc. − are still perfectly capable of doing so even without AI. What it means for iPhone users: Apple unveils new AI features at WWDC 25 The thing that most people are just starting to discover about AI-based capabilities is that they often require changing habits in order to really best take advantage of them. As easy as that may sound, most of us are creatures of habit and asking us to change how we do things is actually harder than most people realize. In addition, it takes training − someone showing you how to really use these new tools − to understand their full capabilities and, as of now, there's precious little of that. Instead, companies are assuming that people can just figure all these new capabilities out and, well, we all know what happens when you assume…. Over time, as we all have more exposure to these new AI-powered capabilities, get a better sense of what they're capable of, and start to learn about how to use them, I have little doubt that we will all become very accustomed to them and will very much notice if they aren't there. In the meantime, however, we're in the early stages of the AI revolution and their presence − or not − still isn't as big a deal as many people believe. So, back to Apple and their situation. Knowing how eager the company is to stay towards the front − but not necessarily lead − on major technology evolutions, I'm certain they wish they did have more new Apple Intelligence features they could talk about right now. In fact, given how important the services side of their business is − and how many opportunities for creating for-pay AI-powered capabilities exist − it's critical both strategically and economically for the company to start creating meaningful AI features. At the very least, it would be great if they could deliver on the impressive vision they demonstrated last year sometime soon. But in the larger arc of time, I feel confident that − as long as they start delivering AI capabilities before mainstream users demand them − the slow rollout of Apple Intelligence features and a more advanced Siri will end up being little more than a bump in the road. In fact, there's a part of me that thinks they might even turn it around and talk about how they'll deliver AI when the capabilities are ready and, most importantly, when we're ready for it. That's a typical kind of Apple message and, honestly, something that, in the end, might just work.

Tariffs vs. Your Paycheck: 4 Ways Trump's Roller Coaster Negotiating Is Impacting Your Budget
The very public feud between President Donald Trump and Elon Musk is bringing up renewed concerns about tariffs. According to The Hill, Musk wrote that Trump and the tariffs will cause a recession. While the Trump administration has said the tariffs are needed to help the American economy, many families are worried about how the roller coaster negotiating will impact their budgets. Trending Now: Check Out: GOBankingRates asked some financial experts to describe how your money is being affected by tariffs. Andrew Lokenauth, money expert and owner of BeFluentInFinance, said basic things like soap and cleaning supplies cost more because of ingredient markup. 'I've watched prices climb steadily at my local stores,' Lokenauth said. 'Just picking up basic home goods costs me about 20 to 30% more than it did before these tariffs kicked in. The other day, I noticed my regular brand of kitchen appliances jumped $75 — a direct result of manufacturing costs getting passed down to us consumers.' Explore More: 'Budgeting pressure from tariffs and higher-priced goods tends to impact Americans differently based on their income levels and spending habits,' said Vince DeCrow, founder of RISE Investments. 'However, many Americans have already started delaying large purchases, downgrading vacation plans and cutting other discretionary spending on things such as clothing, electronics and eating out.' Lokenauth recommends strategic buying to avoid price spikes. 'Timing purchases has become crucial,' Lokenauth said. 'I track price trends and stock up when things dip.' 'If you're nearing retirement or retired and depending on a fixed income, you're likely going to be more heavily impacted by Trump's tariffs,' DeCrow said. 'To plan for this, you can help offset the higher cost of goods by reassessing your budget, prioritizing essential expenses, buying in built at discount retailers and proactively taking advantage of more senior discounts.'

HistoSonics and Cambridge University Unveil Europe's First Edison™ Histotripsy System Powered by Li Ka Shing Foundation Gift
MINNEAPOLIS, United States: HistoSonics, the manufacturer of the Edison® Histotripsy System and novel histotripsy therapy platforms, announced today that Addenbrookes Hospital of Cambridge University Hospital Foundation and Trust will be the first site in the United Kingdom and European continent to offer histotripsy to both NHS and private patients. This was made possible through a generous donation by the Li Ka Shing Foundation (LKSF) as well as the expedited limited market access granted by the MHRA in April 2025. This press release features multimedia. View the full release here: The milestone marks HistoSonics' official entry into the UK and European market. HistoSonics won a coveted place in the Innovative Device Access Pathway pilot in 2024 and through this program, in partnership with the DHSC, MHRA, NIHR, NHSE, and NICE expedited access to patients. HistoSonics will continue to work with UK healthcare stakeholders on our aligned goal of urgently expanding access for all NHS patients. The Li Ka Shing Foundation, established in 1980 by Hong Kong philanthropist Sir Ka-shing Li, has contributed nearly US$4 billion to advancing education, medical research and services, and poverty alleviation across the USA, UK, Canada, and Asia. Recognizing the transformative potential of technological innovation in healthcare, the Foundation's latest gift to the University of Cambridge will build upon its previous donations of five Edison systems with three to Hong Kong, one to Singapore, and one recently to Stanford University. This new gift not only heralds the introduction of the first Edison system in the UK and Europe but also celebrates the enduring partnership between the Li Ka Shing Foundation and Cambridge in their collaborative efforts to fight cancer. By supporting cutting-edge medical technologies that can deliver low cost and highly efficient solutions, the Foundation hopes to enhance patient access with improved healthcare around the world. 'This donation is an historic milestone that brings non-invasive treatment of liver tumors using histotripsy to the UK,' said Mike Blue, President and CEO, HistoSonics. 'We are grateful to the Li Ka Shing Foundation for their visionary support. With Addenbrookes as our first NHS hospital site under UCNA, we are laying the foundation for future expansion into innovation driven hospitals across the UK.' The Edison System, which received FDA De Novo clearance in October 2023, uses non-invasive therapeutic focused ultrasound energy to mechanically destroy and liquefy targeted tissue and tumors without the invasiveness or toxicity of traditional procedures, reducing the risks of bleeding, infection, and damage to surrounding non-targeted tissue. HistoSonics' initial FDA clearance is for the destruction of liver tumors, with ongoing studies focusing on kidney tumors (HOPE4KIDNEY Trial NCT05820087) and pancreas tumors (GANNON Trial NCT06282809). Professor Deborah Prentice, Vice-Chancellor of the University of Cambridge, said: 'We are very fortunate that through the generosity of Sir Ka-shing Li, Addenbrooke's Hospital in Cambridge will be able to use cutting-edge histotripsy technology to improve outcomes for NHS patients. It is technology such as this that allows Cambridge to remain at the forefront of understanding and treating tumors, a position we aim to strengthen further with Cambridge Cancer Research Hospital.' With installations soon to be in five countries including the US, UK, Hong Kong, Singapore and the United Arab Emirates, HistoSonics is actively expanding access to its histotripsy platform and is working closely with clinical leaders, national health systems, and philanthropic partners to accelerate global adoption of histotripsy as a new category of health care. HistoSonics is also pursuing broader UK and European market access via CE marking.
