AI Agents Threaten Google’s Control of Search, Chrome, and Gmail
M.G. Siegler, author of Spyglass.org, argues on Big Technology that Google’s AI risk is shifting from model performance to control of the next software interface. In a conversation with Alex Kantrowitz, he says Anthropic and OpenAI are moving faster in coding agents and computer-use workflows that could make search, browsers, Gmail and other web products less central to users’ daily work. The discussion extends that frame to Apple’s WWDC, Meta’s subscription sprawl and Anthropic’s confidential IPO filing, but the core claim is that the AI race is increasingly about who operates the computer on the user’s behalf.
Anthropic’s IPO Filing Puts OpenAI on the Defensive
Anthropic’s confidential IPO filing gives the company optionality and puts pressure on OpenAI’s public-market timing, M.G. Siegler argued in a rapid-reaction discussion with Alex Kantrowitz. Siegler’s case is that going first could let Anthropic frame the investor comparison between the two AI companies at a moment when its reported growth, profitability narrative and developer traction may make OpenAI’s story harder to sell. The filing, in that view, matters less as an immediate fundraising step than as a move in a sequencing and narrative contest.
