OP's premise is a little off. There will be no extension to be the next .com as it has already held up over the test of time and is universal and in the mass psyche, while other extensions only have niche interest. Also, I don't believe it's valid to say there is no good investment opportunity in .com. I like seeing the optimism for VR taking over as the next platform, but actually, I think .XR would make a lot more sense than .VR. I anticipate both will eventually come to be in the next 10 - 20 years as WebXR becomes widely used. But from a recent experiment, I can tell you all that people aren't ready for WebXR quite yet.
