I started by punching cards, in machine language, to run on a mainframe.
And evolved - Fortran, PCs, Dos .. . The Win’s . ..
We used to know what the computer was doing, and the most efficient way to do a task.
Now it is lucky to get some output, and feel blessed if it looks close.
Computers were to be our ‘slaves’ to make work easier.
Now, they want to command my life.
My first cnc machine still had a punch tape to feed code. Of course I upgraded it but the technology was fascinating to me. 1000 lbs of relays and electronics replaced with a cheapo desktop and a few motor controls the size of a coffee cup.
