Not to mention that the response to each review will come with its own set of new comments and new documentation. The ability of people to write things has exploded tenfold. You can’t out review the slop.
Every PR can be rewritten and re-architected on a whim.
I'm currently not working in tech, but I will again sometime within the next year or so, and I've been reflecting on my career in light of the recent AI madness. I think the biggest mistakes I've made over the last decade+ in tech as a software engineer have been caring. I've worked at small, medium, and large companies. Famous big names you've definitely heard of, less famous ones you probably haven't. In every case, in retrospect, as an individual contributor (non founder, non board member, etc) being personally invested in some outcome--quality, efficiency, cost, ux, customer value--is a mistake.
If you aren't actually in a position to change something, caring about it is futile. [edit] And I don't mean in the sense of "feeling empowered" or some such, but actually having the clout to steer the ship and make it happen. Very few people in a tech organization actually have that power, by design.
The industry wants to do away with code review, meaningful testing, computer security, and reliable services. Why swim upstream? You can't actually do anything about it so why try?
When I go back to work I'm going to do my 9-5 40hr/wk, smile, nod, punch the clock, and make the bosses smile or whatever. But I'll be damned if I'll ever give a shit again.
Because habits beget habits, and in form imprint into your identity. I'm not the biggest fan of GPA fixation, but it does have the side effect of imprinting work habits (I won't say "ethics", because the extremes I saw peers go to to get A's is anything but). It doesn't necessarily imply mastery of your class, but your ability to adjust to someone's standards and meet them. Which is something that will follow you into the workforce, and roughly correlate with people who will meet the standards of their company.
If I don't give a damn about code quality in a place I spend a third of my life, why do I expect to give a damn when I want to work on my own project in the future? Even if I try those habits will wear into something I can call my own. This might be fine if your overall goals have nothing to do with your work; that you are fine just going through the motions and getting a paycheck to empower your non-tech hobbies or focus on supporting your family. But that's not the path I've chosen.
