This mindset of "I don't trust myself to do it" is a bit (sorry) pathetic. I think one should realize that mistakes happen and to a certain extent, though professionals have lower rates of failure, everything is a tradeoff.

Some people have asked me, aren't you afraid you'll make a mistake if you fix your own car? Well, aren't they afraid their mechanic will make a mistake?

I think it's good to realize that AI (famously) also makes mistakes, and not to infantilize yourself to the level of not feeling "comfortable" trusting your own thinking.

Though, I do see younger people today whipping out their phone calculator to "double check" something like a 75% increase on 120.
