The 60x number is real but I know it'll be controversial. It's lines of code in a month vs. what I'd produce in a year by hand. Your mileage will vary. I'm not claiming everyone gets this. I'm saying the range of individual experiences is so wide that averages are meaningless.
Yes, this is another post about vibe coding. But it's a real product with real users at this point, more than a weekend project, and I think the health and communication effects are worth talking about even if the productivity claim doesn't land for you.
Happy to answer questions.
