How big would a typical program be in the 70s?
Imagine someone knocking your shoebox off the table and having to sort them all by hand. Imagine that on your 3rd run, the reader eats one or more of your cards, then they all start to fail.
Programming was wonderous to be sure, but no one is worse off with an IDE and a interpreted language.
Just to be clear: I didn't say anyone is better without and IDE.
