> It would be 18 more years before a new version of HTTP was released. In 2015, and with much fanfare, RFC 7540 would standardize HTTP/2 as the next major version of the protocol.

Huh, this is interesting.

So the current timescale is like:

  HTTP/1: 1996 (though HTTP/1.1 came out in 1997)
  HTTP/2: 2015
  HTTP/3: 2021 (current draft)

Should we expect HTTP/4 around 2022 or 2023, at this increasing rate of progress, then? Just a bit of extrapolation, since it seems like the rate of progress and new versions to deal with is increasing. Promising, but possibly worrying.
