Thank you for your thoughtful answer!

Just to be clear: I haven’t made up my mind yet either :) that’s why I asked a question and avoided delivering truths or anything

Everything you said are all doubts I have, and especially the “it works until it doesn’t” is my biggest fear.

I’m probably less afraid of the “once it stops you’re screwed” part, I have been working in places where taking up codebases and products full of tech debt and renewing them was the norm, so I believe in the worst case that’s still doable.

So I’m not saying it’s an easy and straightforward revolution, yet I’m not so negative about it :)
