That final 30% or whatever takes a lot longer to obtain than the first 70%. Big teams want to ship their chip tomorrow and it needs to work. They don't want any more risk than they're already saddled with so just leave it on the table for next time. I think what you're proposing with less siloing is obviously better (it's the only way I want to work) but it's going to come with a price. There is definitely room in the tooling to help with this, and it doesn't need to involve "AI".
Fair enough, AI doesn't have to be the only solution. But I think some of the verification (at all layers in the stacks) opportunities that AI could be key to make this a reality. (Practically, you need to free up time in order to expand responsibilities without making errors.)
