Kent Beck says YAGNI was never about saving effort. The thread says the essay is AI slop (newsletter.kentbeck.com)
Beck's argument drops the old 'you save typing' defense of YAGNI and replaces it with discounting: build structure now for a feature arriving in three months and you've sequenced cost ahead of return, a loss that lands whether or not your prediction was right.
Half the thread debates the economics; the other half noticed the author's own disclaimer that the back half is a 'genie-generated description of YAGNI', ran it through Pangram, and got 70% AI. One regular: 'I don't know what happened to Kent Beck.'
