Works fine in Chrome

It would be cool to have a non euclidean space telescope though

I see very large web applications from inside. They're not really premade, but we're usually several layers of abstraction above HTML

Well, that's what I see in my company. No one is writing HTML or raw JS or building Rest APIs anymore. Everything is either generated, or behind many layers of frameworks, or both.

Come on, the role of "web developer" has been automated away years ago.

Airplanes will transition to electric eventually. There's some really hard challenges to this, but the progress is being made. More immersive VR and true usable AR will come. There's some really hard challenges to solve (some, like batteries and heat are shared with aviation), but the progress is there. It's not just hardware, software also helps. For example, fast ML computer vision for eye tracking helps foveated rendering, and we're far from done here.

That's not true, fuel efficiency (and range) in commercial aviation has improved a lot in past few decades.
