It wasn't the hard or valuable part of software engineering, but it was a very time-consuming part. That's what's interesting about this new era - the time-consuming-but-easy bit has suddenly stopped being time-consuming.
Agreed, often see cope from managers along the line of “writing the code was never the bottleneck”. Well, sure felt like it.
It's not time consuming. It seemed slow because of all the other important parts of the job. People vastly overestimate how much time SWEs actually spend writing code lol
