WebGL2 has just recently become production quality on all browsers, take all the WebGPU talk with a pinch of salt if you're interested shipping sometihng in the next few years.

(Practically, both are low level APIs and you'll probably be using something that can reasonably easily switch between WebGL2 and possible future WebGPU backends once they finish the spec and implementations start shipping and stabilizing and waiting for Safari)

If you look at it from the perspective of “when will I be able to support 99% of users”, it will absolutely take a few years, but from the perspective of “when will a WebGPU game have distribution to more people than a Steam game”, it could be a lot sooner. Gamers generally aren't the same people stuck on enterprise-pinned old browser versions, so once Chrome + Firefox have support the chances of someone in the target audience for a 3D game having a WebGPU-supporting browser on their system are pretty high.

(I’m assuming you’re talking about distribution rather than tooling, but I acknowledge the tooling will take a few years to catch up.)
