The problem with any project is that at some point it's essentially complete, and all we need is small maintenance to keep it going. Google used to have an algorithm that pretty much solved web search. Tinder solved dating. Spotify solved music delivery. The problem is, you're sitting with a hundred managers and a thousand engineers and all these people expect growth. So you have to keep going, even if the only direction is down, because if you don't, you'll be forced out of organization and replaced by someone who does. So you do go down. And then everyone's surprised and playing the blame game.
