> I feel like the whole impostor syndrome thing has gone too far. At this point, we have legitimately talented developers questioning whether or not they are 'good' enough and it is actually quite frustrating to see.

I'm not sure what you mean by "has gone too far". It's an effect; it's not like people are aiming to feel incompetent. You could just as well say that "This depression thing has gone too far" -- OK, but so? That's not a solution? Sweeping it under the rug doesn't cure anyone of it.

The solution to imposter syndrome is to make everyone aware of it, so that people who could otherwise grow into their role properly don't look around at the performance of their more experienced peers and simply give up. At my work we assign all new employees a more experienced mentor that they can discuss these issues in confidence with. It really helps.
