ARPANET dates to 1966. You could have said the same thing in 1981: So when is all this stuff going to happen? Every time someone comes up with a criticism the solution will come later because it’s “early days”.

Should we have given up on the internet by 1981 then?

Sometimes new technology takes a few (human) generations to take off. I know everyone wants instant gratification these days, but try to be patient.
