I remember playing a crap web game in college, kinda like gunslinger, where you try to shoot people who turn around with a gun (and not those without). When I graduated college, Ian--one of my good friends at work--ended up being one of those guys in the game! Turns out that game I was playing was built by Tom Fulp, and he was using his friends (like Ian) as characters in his games pre-Newgrounds. All that messing around with crap games on the internet paid off. He had started Newgrounds while in college, and had quit to do it.
Met Tom once, and he was a cool guy, but he didn't believe in the stuff that they taught in CS. He had a long rant about how learning string diff algorithms were useless. Anyway, it turns out later on, he went back to college to finish his degree. When his classmate(s) found out who he was, this one kid was so excited to sit next to him. "Do you know who he is?!" he would exclaim to his professor, to Tom's embarrassment. I wonder if he had to do string diff algos when he went back to finish college.
I worked at bigcorp for half a decade before all of the LLM stuff and there was exactly one time I really had to give a shit about algorithmic complexity in that entire tenure. Obviously some developers needed to care more than others, but the vast, vast majority of work and roles just didn’t really need to care about this. 9 times out of 10 you’re using the off the shelf library that already has the optimized bubble sort of whatever for your job
Working at bigcorp for 14 years so far and I struggle to think of a single day where I didn't need to consider algorithmic complexity or efficiency. Do you not write code that fetches things from a database? Do you not need to make tradeoffs between how much data you fetch at once, which fields you load, which things you cache, whether your query joins on the db or materializes things separately, whether you lazy or eager load, whether you are doing a O(1) or O(n^2) lookup and the tradeoffs, whether you can use a db index or not, memory/latency/compute/storage tradeoffs, etc? I feel like in even a simple bigcorp SAAS you need to consider this stuff daily.
