Is there not some part of you deep down that looks back at the last decade of technology and feels "well I'm glad we're not doing things that way anymore, it was totally wrong for our situation"?

It just seems that that is constantly the case. We might well be another 3 or 4 decades away from software development technology hitting real maturity in terms of really streamlined tooling, frameworks, languages that help us work at the right level of abstraction at the fastest speed.

I don't think it's an entirely unwarranted comment. I think it's wise to constantly be thinking about and looking for "what awfulness are we accepting as a trade-off to get the great benefits of this particular way of configuring our process?"

By all means get into the hype, dive in, be excited. But don't forget to shit on yourself because you know the shit is coming at some point. If not in 5 years then in 10. It'll help you see it coming.
