Ye, SE Lain has lots of tech reference. This website lists many of them: https://www.cjas.org/~leng/lain.htm

That was the most prophetic and in my opinion, best anime to date about technology. They predicted SO much about today back in one of the most excellent short anime's of all time.

"Present day, heh, Present time, AHAHAHA"

Even the fansites are AWESOME: https://fauux.neocities.org/ (click "go visible", and keep clicking on lain)
