I don't believe that these limitations have been engineered away in all
parts of the Internet (depending on how far you believe the Internet
extends).

Mobile wireless networks may still have limited and/or rapidly varying
bandwidths.

I understand that many wireless tactical networks still have fairly
limited bandwidths.

mmWave 5G service seems to have made this worse.  Bandwidths,
even connectivity, can vary rapidly and dramatically, over short
time frames and distances. See, for example,
