Indeed, this submission is also a good article on why pair programming often fails with humans.

It's not that AIs are bad. It's that pair programming is (often) not effective. In the majority of cases, one side dominates the other.

In my experience, a modified pair programming system works better where the two of us discuss the problem to be solved, then each of us goes off for a few hours independently coming up with ideas, and doing experiments. We then get together, discuss our findings, and finalize a plan of attack. And then pair programming helps as we're both at the same level and on the same page. But even then, having to watch someone else's screen (or have people interrupt you while you're typing) is a pain.
