I'm not so sure, and I'm a native Russian speaker, who had read the original Russian language post just to make sure of this. That guy genuinely sounds unironically arrogant to me.

It's much harsher in Russian than the English translation. Compare:

> You'll sit next to me and memorize the way the work should be done.

and

> А ты, бездарь, сиди рядом и запоминай, как работать надо.

which literally translates to "And you, bungler, sit and watch how the work is done [right]."

And I utterly fail to see any self-deprecating piece that would turn this into a joke. If anything, author treats those "Google"-programmers as trash.

Even as a joke, I would say it's very poor and distasteful one, especially for a public blog post.
