I think big corporations are just structurally unable to create products people actually want to use. They have too much experience with their customers being locked in and switching costs keeping them locked in. Anthropic needed a real product to win mind-share first, they will start enshitifying later (by some accounts they may already have). The best thing a big corporation can do with a nascent technology like that is to make it available to use to everywhere and then acquire the startup that converts it to a winner first. Microsoft even fumbled that.
