I think the point about grass being greener is a good one in general, but I have to say that I'm wording things specifically to account for this: I want
other problems than the ones I have now. I don't like the problems modern distributed systems development present me with anymore. It's boring and I genuinely feel like we keep having issues that shouldn't even be issues because of the technologies we use and the layers/systems that have been added to everything.
I will also say, having worked at game studios before I believe them to have a much better barometer for what is extraneous, so even the live services teams at these places tend to be a lot more sensible than your average web shop. Your mileage may vary, though.
Games as a service and de-risking large projects I'm not sure is that relevant? Someone has to work on the engine, the networking code, and so on, and this work is largely not really going anywhere. There have been approximately zero innovations in the last 20 years that remove the need for being able to write lower-level code and knowing the internals of a game engine, provided you want to make something half-way decent.
Even if game studios somehow manage to not do the work I'm interested in, I might just take an extremely long sabbatical while continuing to make games and work on those things.
There is an alternate future where I also try to create custom solutions as a contractor in performance-critical niches and still work primarily with backend stuff, but I'm not sure what that would mean.
