There is the software side to classic computing: Back in the early days we wrote/coded in BASIC-TinyBASIC running in 2K(talk about writing efficient code!); EASY and SmallFORTRAN. What apps/programs are written in today I don’t know. They certainly can’t run in 2 or 4 K but is the outcome the same – make a computer or computer-like machine do what we want it to.
On the lighter side: “Computers can never completely replace humans. They may become capable of artificial intelligence(much in the news today), but they will never master real stupidity.” Happy computing all. Murray :)
