In some respects, a modern mobile phone has more in common with minicomputers than minicomputers had with computers before keyboards and file systems. Being able to interact with computers in a meaningful way transformed computers from programmable calculators and data processing machines into something entirely different. I would imagine that more people have seen those archaic computers in museums than during their service life simply because there was no need to interact with those computers back in the day. Even a web developer has more direct control over a server in a data centre than most early programmers had over early computers. (At least those used in businesses. Computers used for research were a different story.)
