I think the author's dislike for pair programming says a great deal more about the author than it does about pair programming or LLMs.
If you're pair programming and you're not driving, then it's your job to ask the driver to slow down so you can understand what they're doing. You may have to ask them to explain it to you. You may have to explain it back to them. This back-and-forth is what makes pairing work. If you don't do this, then of course you'll get lost.
The author seems to take the same passive position with an LLM, and the results are similar.
