Kind of will. There are already templates on demand for things like generating unit tests as you code. They’re pretty robust already, and have aside from a few things (or edge cases), I don’t have to do much code refactoring or fixing them.
They already save me several hours a week from manually setting up full ones. Haven’t delved into other stuff they can do, but I’m sure it would only be more useful with time.
I can very easily see companies looking at the time save and thinking “we can downsize”.
I actually do. Upscaling, fast forwarding, modding, cheats, save states are all nice QoLs. A lot of emulators for these retro consoles are pretty platform independent too, so I can run them from anything from a PC, a handheld device, phone, other gaming consoles or smart fridge with my choice of peripherals.
