I think it's talking about people who don't know how to read code and discern what's happening and just end up tweaking things, cutting and pasting code, etc. just kind of crossing their fingers that it will work.
My understanding of the Feynman Algorithm was that it was basically a joke by Gell-Mann. Gell-Mann was pointing out that no one else on earth (even himself, a Noble prize winner) could work the way Feynman did, the joke being that he only needed three steps: (1) Write down the problem. (2) Think real hard. (3) Write down the solution. It was about the absurd brilliance of Feynman, not intended as any sort of useful model to follow.
