There's certainly some aspects of bullshittyness to it all, but I find it exciting. It's cool to see new ways of doing things coming into the industry and people trying to improve. I think when you start thinking that it's all or mostly all negative and "hype", then it's time to maybe look for a new role (I mean this in a very positive way - not trying to be rude here!). If you're 30+, have a ton of engineering experience and are starting to feel bored - look for maybe how you can leverage your years of skills and experience in a new role that you can really get excited about. Life works in chapters, being at the end of one (in terms of motivation/passion) isn't a bad thing. It just means you're ready for the next one.
The cynicism also comes from the fact that all these "improvements" are just well known existing techniques coming into and falling out of fashion. I do agree that finding a new chapter is a productive approach. It would be nice to find a physical job that doesn't pay peanuts and where you don't get treated like shit.
