I read hubris here as...you want to be the best, you don't want to be criticized, so you will work hard and be super motivated to make your program work very well, handling all the various edge cases, making it better than the competition.
Yes, but that is not what the word hubris means. It means pride in the seven deadly sins sense. The pride that comes before a fall. Hubris would not mean working hard to reduce the scope for criticism. It would mean not accepting valid criticism because you think you are better than the critics.
He could have just used the word "pride" (which is far broader and has positive meanings too) instead. In some ways "ambition" might be a better fit.
Ambition might stand out in the same list as laziness. Plus I'd be reticent to tell programmers to "be more ambitious!" - I see greenhorns esp just trying to do too damn much at once.
In the context of "code that is going to be reviewed" maybe even "vanity" might have been closer to what he was getting at? (did you even RUN this?) Except us old neck beards obviously don't care about how WE look ;)} - just how our code reads.
I think "take pride in your work" would have substituted well; but given the options, maybe hubris was fine - he explains what he means in a couple of sentences.
