I don't think it'll go that way, i remember when web workers first came out i wrote a simple raytracer with some GI and optionally used web workers if available for multiple threads. It worked fine until some browser updates later that limited the amount of web workers pages could use (or the amount of time each worker got, i don't remember, it has been a few years) making the web worker version have pretty much the same speed as the regular version.
