Well, it certainly depends on the culture of the team and organization.

Where you have shared ownership, meaning once I approved your PR, I am just as responsible of something goes wrong as you are and I can be expected to understand it just as well as you do… your code will get reviewed.

If shipping is the number one priority of the team, and a team is really just a group of individuals working to meet their quota, and everyone wants to simply ship their stuff, managers pressure managers to constantly put pressure on the devs, you’ll get your PR rubber stamped after 20s of review. Why would I spend hours trying to understand what you did if I could work on my stuff.

And yes, these tools make this 100x worse, people don’t understand their fixes, code standards are no longer relevant, and you are expected to ship 10x faster, so it’s all just slop from here on.
