Agree. That's fallout from web becoming soooo complex. You have webasm. WebGl. JS compilation. WebRTC. Like a hundred other techs you need.

In the old days, a small team could make its own engine. There wasnt' so much to it. Now, only like 3 co's in the world can. And one of the 3 is propreitary for only their own hw.

There's Gemini ofc. But I doubt it will ever catch on outside like 0.001%.
