1. Google recently started an AI inbox service, which summarizes the most important messages of unread emails. For those who are sucked into unread emails, a selected list of new messages will come in handy. As for me, I would like AI to handle my cumbersome email management. But here's the thing - is AI trustworthy?
According to Nicold Nguyen, a Tech columnist from The Wall Street Journal, she shares a pleasant experience with Gemini, an AI by Google. Aside from the email-assistant role of Gemini, she first leverages the ghostwriting function, where she appreciates the friendly tone('Help Me Write') and the intelligent feature of the function('Suggested Replies'), which mimics the writer's tone. The writer reports in a considerate manner that she felt uncomfortable using the ghostwriting feature with her loved ones. However, the feature will come in handy with a vast amount of email workload, she added.
The new feature of Gemini not only includes the editing part, but also includes the "AI Inbox" part, which prioritizes unread emails. The feature also extracts action items and compiles them into a skimmable report. There are two main features: to-do's and topics to follow. AI Inbox prioritizes messages using signals such as people you email frequently and relationships it can infer from the message content. The to-do's and topics refresh regularly, depending on how much email people get. It isn't meant to replace the inbox stream; it's a separate section above the regular inbox.
Google is restricting AI Inbox to "trusted testers" before making it more broadly available in the coming months.
In Google Labs, there are other interesting tools; CC is an AI-powered productivity agent that emails people a daily briefing based on the contents in Gmail, Google calendar and Google Drive. Personal Intelligence, which is only for Google AI Pro subscribers, lives in the Gemini app. When a person asks for a certain thing that cannot be inferred from Gmail, the AI broadens its inspection scope to other Google account-related apps, like Google Photos.
Email is not currently replaceable by AI, but if it can be optimized using AI, I would definitely want to use it.
2. Out of the 7 best-invested groups, the so-called Magnificent Seven, only Alphabet and Nvidia outperformed the S&P 500 in 2025. And so far this year, the other five stocks are faring worse than the broader benchmarks. Money managers say that Microsoft, Meta Platforms, Apple, Amazon.com and Tesla are no longer synonymous with stock-market stardom.
AI trade has evolved ever since the raging bull market began, but investors are now betting more cautiously than before. Some expect that the benefits of AI will spread to broader industry, while others are doubling down on the chip makers or the energy companies they expect to power the build-out. Michael Hartnett, a BoA strategist, points out that the next Magnificent Seven will be the companies that show that AI adoption is transforming their huge businesses, and only a few will survive.
Individual investors, many of whom were loyal shareholders of the Mag Seven have also started turning their attention to other parts of the market. According to Vanda Research, the volume of these shareholders' proportion in the overall trading volume has significantly decreased compared to what they did in 2023 or 2024. Tesla, for example, has seen a 43% drop in retail turnover in 2025 compared to two years before. Harnett said he initially grouped the stocks based on their shared characteristics as huge, well-run companies that were dominant in the tech sector. But the AI arms race has been driving a wedge between members of the Mag Seven for some time. Amazon, Alphabet, Microsoft and Meta are spending hundreds of billions to train new AI models, build data centres or expand cloud-computing capacity, and Nvidia still dominates the market for the chips needed to power the most advanced AI models. Meanwhile, Apple and Tesla are lagging; Apple faced criticism for spending less and losing ground to competitors on AI efforts. Tesla stocks are underperforming as sales of its electric vehicles have slowed.
Regardless, the companies are swimming at their own paces, and the winners and losers are somehow going to be chosen, Michael Arone, a chief investment strategist at State Street Investment Management pointed out. While the companies might be in different stages, each of the companies still has an outstanding influence on the market. Together, they comprise roughly 36% ofthe S&P 500's market capitalization. The Mag Seven may have lost some of the reasons to link them altogether, but for now, their positions hold firmly in their own positions.
