Well, as along as we continue to build NATworks on the assumption that
everyone is a consumer, not a citizen, that pattern will continue to happen.

I think that when FACEBOOK suggested such a thing, explaining how they could
accelerate everything through their servers, it was a major problem.

Had this been the attitude in 1989, then the Internet would never have
happened, and WWW would not have been a thing.

The lockdown has shown that actual low-latency e2e communication matters.
The gaming community has known this for awhile.
