Google has made changes to how it collects app store fees in the past, the most significant being in 2021, when it lowered its cut to 15 percent on the first $1 million developers earn, and 15 percent on subscriptions. The difference here is that the regulatory scrutiny brought about by Epic's lawsuit against Google and Apple seems to be a key motivator for its changes. Well, that, and an entirely separate business deal the company made with Epic. Google and Epic's settlement served as the basis for these changes, but The Verge reported in January that the companies also agreed to an $800 million joint partnership around product development and Google using Epic's "core technology." Letting developers keep more of their money is ultimately good, but it's a business decision Google felt comfortable making, which likely means it has its own share of upsides.

A small, trusted kernel: a few thousand lines of code that check every step of every proof mechanically. Everything else (the AI, the automation, the human guidance) is outside the trust boundary. Independent reimplementations of that kernel, in different languages (Lean, Rust), serve as cross-checks. You do not need to trust a complex AI or solver; you verify the proof independently with a kernel small enough to audit completely. The verification layer must be separate from the AI that generates the code. In a world where AI writes critical software, the verifier is the last line of defense. If the same vendor provides both the AI and the verification, there is a conflict of interest. Independent verification is not a philosophical preference. It is a security architecture requirement. The platform must be open source and controlled by no single vendor.
Less encouraging is that you'll see these tools referred to as "addicting" or even "the best friend you can have". While nerds being utterly drawn to computers is as old as the PC revolution itself, there doesn't seem to be an associated cambrian explosion of creativity and accomplishment to go with it.
