First of all ignore the trends. Fuck docker, fuck nixos, fuck terraform or whatever tech stack gets shilled constantly.
Find a tech stack that is easy FOR YOU and settle on that. I haven't changed technologies for 4 years now and feel like everything can fit in my head.
Second of all, look at the other people using commercial services and see how stressed they are. Google banned my account, youtube has ads all the time, the app for service X changed and it's unusable and so on.
Nothing comes for free in terms of time and mental baggage
