The VAST majority of developers I've encountered aren't interested in building sustainable codebases. Mainly that's because that's not what their bosses want so it's in their best interest not to care about it. I could see the same happening if the economist's bosses don't care about sustainable economies.

Depends on the developer and on their organization they work for. Ideally, most do, but the pressures of work and the styles of project management sometimes sideline that, or the team ends up in survival mode where they merely try to stave off the inevitable spaghetti apocalypse

Just for the record, no one in AI (the space where increasingly all of code is moving to) cares about building "sustainable codebases".

Worst code quality: AI devs

Best code quality: Game devs

> Game devs

LOL I just read something yesterday (possibly a tweet by Carmack?) that game devs optimize for public perception of their game and that is it. Certainly not long term maintainability unfortunately!
