One ChatGPT query uses same energy as a second of baking, OpenAI says
A single query to the AI software ChatGPT consumes as much electricity as roughly one second of baking something in an oven, according to the developer OpenAI.
Meanwhile the water consumption from each query - owing to data centres needing to be cooled - comes down to about one-fifteenth of a teaspoon, OpenAI chief executive Sam Altman wrote in a blog post.
Experts have for years been warnings about the massively escalating energy demands from the widespread use of AI services. While individual queries may require less energy due to efficiency gains in chip and server technology, the sheer volume of usage continues to drive a sharp increase in energy demand for AI data centres.
Companies such as Microsoft, Google and Amazon are planning to rely on nuclear energy in the US to help meet this demand without proportionally increasing emissions of climate-damaging carbon dioxide.
The need to cool data centres has also raised concerns about water consumption. In recent years, several studies have attempted to calculate the environmental impact of increased AI usage, but researchers must rely on numerous assumptions.
Altman shared OpenAI's energy and water figures in a blog post in which he painted a generally positive picture of the future of AI.
He acknowledged that there would be significant disruptions, such as the elimination of entire job categories. "But on the other hand the world will be getting so much richer so quickly that we'll be able to seriously entertain new policy ideas we never could before."
In recent years, the idea of a universal basic income, funded by productivity gains, has been discussed in connection with AI.
According to the OpenAI chief executive, an average ChatGPT query consumes approximately 0.34 watt-hours of electricity ("about what an oven would use in a little over one second, or a high-efficiency lightbulb would use in a couple of minutes").
He quantified the water consumption at 0.000085 gallons (0.00032176 litres). Altman did not provide further details about the basis for these calculations.

Microsoft Hits an All-Time High. Here's Why These 2 "Magnificent Seven" Stocks Could Be Next.
Companies that find new ways to grow earnings can be incredibly powerful investment opportunities. Paying a reasonable price for a quality company is better than paying a dirt-cheap price for a poor business. A strong balance sheet can make a big difference during challenging times. 10 stocks we like better than Microsoft › Microsoft (NASDAQ: MSFT) hit a new all-time high early on Wednesday -- making it the only company at the moment valued at a market cap over $3.5 trillion. Investors wondering which "Magnificent Seven" stock could be next to have come to the right place. Here's the case for why Meta Platforms (NASDAQ: META) and Nvidia (NASDAQ: NVDA) could follow in Microsoft's footsteps and soon hit all-time highs, and why both stocks are worth buying now. The simplest reason why Meta and Nvidia could quickly follow Microsoft and hit all-time highs is because both stocks are the next-closest Magnificent Seven members to their all-time highs. Meta and Nvidia may be close to making new highs, but it's a mistake to buy a stock just to make a quick profit. A better approach is to invest with a long-term mindset, and Microsoft, Meta, and Nvidia have the qualities necessary to be excellent investments for years to come. Microsoft, Meta, and Nvidia may operate in different industries, but they have many similarities as businesses. All three companies have done a masterful job carving out high-margin operations in competitive, growing industries. Microsoft has transformed its business from legacy software and hardware to the No. 2 cloud computing player behind Amazon Web Services (AWS). It has also leveraged artificial intelligence (AI) across its operations to boost efficiency and grow profit margins. Instagram became such a prevalent social media app that Facebook changed its name to Meta Platforms to showcase the company's Family of Apps and virtual and augmented reality investments. Instagram has undergone a makeover from a stagnant, gallery-like interface centered around images to a dynamic platform with videos and an engaged community tailor-made for viral content. Instagram has helped Meta expand its revenue and margins and stay highly competitive with other short-form video options, like TikTok. It wasn't long ago that Nvidia heavily depended on its graphics segment, which includes sales for gaming, PCs, visualization, and software for internet applications. But now, the company's compute and networking segment makes up the vast majority of operating income and is the company's main growth driver, as customers demand supercomputing platforms that can handle increasingly complex and large data sets and simulations. In Nvidia's latest quarter, which was the three months ended April 27, compute and networking brought in $39.6 billion in revenue and $22.1 billion in operating income, compared to $4.5 billion in revenue for graphics and $1.6 billion in operating income. For context, Nvidia's compute and networking for the same quarter just one year ago was $22.7 billion and $17.1 billion in operating income -- illustrating the segment's breakneck growth rate. In sum, Microsoft, Meta Platforms, and Nvidia have undergone considerable transformations in recent years. Newer business segments are arguably the most valuable part of each company -- cloud for Microsoft, Instagram for Meta, and sales for data centers for Nvidia. When a company evolves, it can take the market time to properly value the new business. Microsoft, Meta, and Nvidia crushed the S&P 500 (SNPINDEX: ^GSPC) over the last five to 10 years, especially Meta and Nvidia. And yet, because all three companies are growing profits from their legacy business segments and new markets, their valuations are still reasonable. Microsoft and Meta both have slightly higher price-to-earnings (P/E) ratios than their five-year median levels. Nvidia's P/E ratio is down considerably since the company wasn't as profitable a few years ago. As you can see in the chart above, expectations for Microsoft and Meta's forward earnings are fairly bleak, since their P/E ratios are just a little higher than their forward P/Es, suggesting low earnings growth. Meanwhile, Nvidia is still expected to grow quickly (but not as quickly as in the last few years), so its forward P/E is a lot less than its present P/E. Still, all three stocks may look expensive at first glance compared to the S&P 500, which has a forward P/E of just 21.7. But given the industry-leading positions of all three companies in rapidly growing industries, their valuations are arguably justified, especially relative to other hot stocks. Walmart (NYSE: WMT) and Costco Wholesale (NASDAQ: COST) -- the two most valuable companies in the consumer staples sector -- trade up 139% and 115%, respectively, over the last three years compared to a 46% gain in the S&P 500. But they haven't backed up those gains with considerable earnings growth -- leading to a valuation expansion for both stocks. Walmart has a sky-high P/E ratio of 41.6, and Costco is even more expensive, at 57 times earnings. In an era when investors pay a premium price for high-quality companies across stock market sectors, Microsoft, Meta, and Nvidia aren't that expensive compared to many other names. Another similarity between Microsoft, Meta, and Nvidia is that all three companies have impeccable balance sheets. Microsoft finished its latest quarter with $79.6 billion in cash, cash equivalents, and short-term investments, compared to just $39.9 billion in long-term debt. In its latest quarter, Meta reported $70.2 billion in cash, cash equivalents, and marketable securities, compared to just $28.8 billion in long-term debt. Nvidia had $53.7 billion in cash, cash equivalents, and marketable securities, compared to just $8.5 billion in long-term debt on its balance sheet in its latest quarter. Each company has at least twice as much cash, cash equivalents, and investments as long-term debt, providing an elite level of financial health. Having a strong balance sheet can come in clutch during an economic downturn, a slowdown in a key end market, or a compelling acquisition opportunity. Microsoft, Meta, and Nvidia are ultra-elite Magnificent Seven companies due to their established and legacy business units, opportunities in newer industries, reasonable valuations, and balance sheet strengths. There are the kinds of businesses investors can be confident buying and holding over a period of at least three to five years. It's never easy buying a stock near an all-time high. But if a company continues boosting its earnings year after year, it can grow into its valuation. This concept is why it's better for long-term investors to focus on quality companies than trying to get a weak business for an inexpensive price. Or, as Warren Buffett famously said, "It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price." I'd say that Microsoft, Meta, and Nvidia are three wonderful companies at fair prices, making them great candidates for investors to load up on in June.

Google Chrome Warning Issued For Most Windows PC Users
Beware this hidden Chrome threat. This is another interesting month for Google's 3 billion Chrome users, with a U.S. government mandate to update all browsers by June 26 and another update warning this week as further vulnerabilities are discovered. But there's a very different Chrome threat to your PC, and it's much more difficult to find and fix. Already this month we have been warned by LayerX that 'a network of malicious sleeper agent extensions" are 'waiting for their 'marching order' to execute malicious code on unsuspecting users' computers.' A huge number of Chrome users have at least one extension installed, which is one of the browser's biggest security risks. Now Symantec warns that some of the most popular extensions it has analyzed, 'expose information such as browsing domains, machine IDs, OS details, usage analytics, and more.' The research team says 'many users assume that popular Chrome extensions adhere to strong security practices,' but that's just not the case. Symantec found that even some big-brand extensions 'unintentionally transmit sensitive data over simple HTTP. By doing so, they expose browsing domains, machine IDs, operating system details, usage analytics, and even uninstall information.' More alarmingly, 'because the traffic is unencrypted, a Man-in-the-Middle (MITM) attacker on the same network can intercept and, in some cases, even modify this data, leading to far more dangerous scenarios than simple eavesdropping.' Bugcrowd's Trey Ford told me 'this is a very common way to compromise browsers for various outcomes, ranging from stealing credentials and spying on users, to simply establishing ways to very uniquely identify and track users across the internet. Ultimately this can manifest as a form of malware, and unavoidably create new attack surface for miscreants to attack and compromise a very secure browsing experience.' There's no easy answer to this one. Symantec says that while 'none of [the extensions] appear to leak direct passwords,' the data can still fuel attacks. 'The risk is not just theoretical; unencrypted traffic is simple to capture, and the data can be used for profiling, phishing, or other targeted attacks.' Symantec notified the developers behind the tested extensions (details in its report.) 'The overarching lesson,' the team says, 'is that a large install base or a well-known brand does not necessarily ensure best practices around encryption. Extensions should be scrutinized for the protocols they use and the data they share.' According to Keeper Security's Patrick Tiquet, 'this highlights a critical gap in extension security,' if and when 'developers cut corners.' He warns that 'transmitting data over unencrypted HTTP and hard-coding secrets exposes users to profiling, phishing and adversary-in-the-middle attacks – especially on unsecured networks.' The risk is especially acute for enterprises. 'Organizations should take immediate action by enforcing strict controls around browser extension usage, managing secrets securely and monitoring for suspicious behavior across endpoints. Just because a browser extension is very popular and has a large user base doesn't mean it's secure. Businesses must scrutinize all browser extensions to protect sensitive data and identities.'

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
