More generally, the stuff which looks hilarious in older sci-fi, is technological stuff which is surpassed in the real world.
Awhile ago I was watching the movie Johnny Mnemonic. It was amusing how Johnny's brain implant could only hold 60 gigs of data.
Though back then in the early-mid 1990's, 60 gigs appeared to be a lot of memory or storage space. One of my computers back then had 8 megs of ram memory and a 500 meg hard drive.
