Because as opposed to what many people like to think, and even though tech is a purely desk-kind-of-job; tech doesn’t actually require deep intellectual thinking.

Tech is the least risky engineering discipline and in the huge majority of jobs requires the level of a plumber work with almost none of the liabilities of physical manufacturing.

So of course a lot of us have impostor syndrome as we’re simply not doing anything special (but also the job doesn’t actually require anything special either)
