Some of us will even remember when compilers ran on big central computers, and you might have to wait 15–30 minutes to find out if your code was syntactically correct (let alone if it worked.)

My father remembers when he wrote code printed on a set of punched cards, they traveled several hours on an evening train to a warehouse with a big government statistics computer (that was too busy during daytime), the result came back by train next morning. Syntax error? try again tomorrow…
