They"ve basically got the dates pretty wrong. It's make sense if they'd said 35 years ago, that's when it was common to know that.

I'd say almost all of that became redundant for the average person with windows 3.1 release (34 years ago) or, maybe, more windows 95 (31 years ago).

I remember desperately trying to get two computers to talk to each other so we could play doom in the early 90s, whatever black magic we had to do seemed to take hours to get working.

The time we had 3 or even 4 computers playing Baldurs Gate together I swear we started trying to get the computers talking at 7pm and didn't start playing till 10 (but it was amazing).
