If rust still has people talking about missing C++ for faster compile times I don't think anything has solidified yet.
All we seem to be doing is make more layers of gray goo and leaky abstractions that we then plumb together to attempt to make reliable systems. It still doesn't feel right to me.
You must be living in some alternative universe. What I typically come across, even in fairly young companies, is tech debt ridden, buggy, endless cakes of layer upon layer of mostly cruft with a spiffy looking front thrown over the whole. Pretty icing on a crappy cake. As soon as you lift that top layer the illusion crumbles. I'd be happy to bet that most companies that run services out there would not survive a hostile audit of their code and systems.
