It's worse than that - imagine if you had a team focused on a pie in the sky AI-based UI that ran on Fuchsia, but over-funded that, and it went nowhere, so it was killed, and then all of a sudden an LLM came out and all the miraculous UI parts seemed possible, but you were stuck with poorly run Android?
