>As an artist, I want my games to be 1080p with unlimited colors and animation.

For an artist you don't seem to understand artistic intent, statement, the power of limitations, and stylization.

>Pixel art looks like stitching. When will everyone grow up?

Again, this is not an "artistic" judgement, and it would be laughed off in any actual artistic school. Artists choose their tools and impose all kinds of stylizations and restrictions on themselves.

There's nowhere in aesthetics that says "more X = better art".

That would be like talking down on people playing americana music because we now have Techno and EDM and modern tools...

Well, it actually runs on low end hardware with that resolution. It's also meant as educational tool, and for kids creating small pixel sprites is certainly easier than high res high quality graphics.
