I love homebridge. Out of the 100 devices or so that I have in the HomeApp, only 2 or so are „native“ HomeKit devices. Will upgrade to HomeBridge 2 soon (but keep my old installation just to be safe =))
We already do this with libraries and frameworks in a more primitive way. The hard work is actually done by a hand full of programmers, everyone else is sticking pipes together. I don't think that's a bad thing per se, but in my experience most people don't make the distinction. You're not going to be able to write your own database server with this tool if you weren't able to do so without it. If you're one of the few programmers that are able to build a database, a graphics engine, a compiler etc. you're fine. Everyone else should probably feel a mild panic. You'll be automated away in a couple of AI generations.
Another weird thing: I have a 3DS and a 3DS XL but purchases can only be installed on 1 system. This is also a problem if your system breaks, because your games are tied to your console.
