As long as using samples in a tracker counts as "making chip", then I'll be doing this forever. Whether it sounds like video games or not, well, fuck it.
Now, about the lack of growth or development of the "scene"... There's been a trend towards EDM in all music in general for the last decade. That will go away, probably sooner than later. I don't know if it will ever disappear from chiptunes, though. Think about how easy it is to make 4 On The Floor stuff in a tracker. Really fucking easy. There's more to it than just holding "Z" with a space value of 4 or 8, but basically, it's really fucking easy.
Then there's the use of pattern chains as the structural method, which lends itself to EDM production, and the use of common synthesizer waveforms in many different platforms for chipmusic creation, which also lends itself to EDM production, and it starts to seem like chipmusic and it's means of production is almost purpose made for EDM. It's not, but it's easier than attempting Beethoven using the same means.
Also, many of the older tracker group music disks were mostly an EDM genre of some sort. House, techno, jungle. The popular 90's stuff. It wasn't technically chiptunes but it's part of the heritage.
I personally prefer the ultra-melodic, European tracker stuff, like this:

That, and the other music like it, is what I have always thought of as chiptunes. Before I ever found this forum, or attempted making chip myself, I listened to tunes like that and imagined there was a world out there of musicians who were virtuosos with melody.
I came to find that currently, chipmusic IS mostly just EDM that's been realized on a Gameboy, but there are still people out there doing the melodic stuff, and those out there doing other things beyond, as well. EDM works well for live shows. It works well with the most popular non-tracker software, like Live. It's easier to get into than learning scales and theory, although maybe that's contentious because it requires it's own separate set of rules.
Of course, it all comes down to the fact that "chiptune" is one of the niche-iest of niche genres, and no one but people like us will even give two hoots about it. It's probably better to appreciate what you like, ignore what you don't, and try not to eat each other alive when there's only a population of MAYBE tens of thousands to begin with.
