I’ve seen people use notepad and I’ve seen people who are so good at vim that they look like they’re on editing code directly with their mind.

Your particular example is extreme and my guess is the coworker is just not great at debugging. I use Claude all the time for finding bugs, but it fails fairly frequently though. I think there’s probably advantage to having some people who don’t use it that often, so you have someone to turn to when it fails.

I’m definitely not exercising my debugging skills as much as I used to and I’m fairly confident they’ve atrophied.

Most execs didn't get where they were by being truly helpful and adding value to the company. They played the game long enough to know that politics trumps accomplishments. The rest from there is the ability to weave a good story (be it slightly or completely exaggerated).

It's not even about trust. It's about incentives in a structure that is dog-eat-dog. Rugged individualism in a corporate structure is a self defeating prophecy. But it's inevitable when executives extract from the company instead of rising the tides for all ships. And shareholders reward it.
