When you're so out of touch as to not know who Kent Beck is, these questions hardly matter.
The thrust of the issue is that: when used suitably, AI tools can increase the rate of learning such that it changes the economics of investments in juniour developers - in a good way, to the contrary of how these tools have been discussed in the mainstream. That is an interesting take, and worthy of discussion.
Your appeal to authority here is out of place here and clearly uninformed, thus the downvotes.
I know who Kent Beck is and I'm not impressed by Agile and Extreme Programming.
What I did not know and what the Wikipedia page revealed is that he worked for a YCombinator company. Thus the downvotes.
