Awareness of your own limits, and the likely quality of your work, is a good thing.

But this descends into self-flagellation. Waaaah, I suck, you suck, we all suck. We're all the equal-worst programmers EVER.

If you're doing research into programming languages, and you're explaining your work, or asking for funding, fine.

But coming from practicing programmers, it's a common, trite, pointless and irritating refrain containing zero useful information.
