Would like to know how much it costs per day.

About as bad as I expected. AI can write code I don't feel like - but I still review and understand every line like it is a proven untrustworthy coworker (most are proven trustworthly and get a lesser review). I have found too much outright bugs, race conditions, changing standard required constants and the like.

I don’t understand what he’s actually building with 37k loc/day. In a month that’s 200k loc per project. I tried to go look at his blog but it didn’t load on my phone.

>argued that Gregorein belongs to a fading era of software development, when humans still checked code, line by line, before shipping. I guess people are going to hurt themselves badly before they realize this is still a requirement.

Just once I wish they would talk about the product they actually shipped

I get it. This is an 10x ai developer. It's the additional line count to get one good line of code.

I still don't understand this trend of measuring productivity by lines of code shipped. Goodhart's law can apply to any metric but this is an exceptional bad and gameable one.

So we’ve finally reached the typing monkeys - since one line in a million might be Shakespeare. I went all in on Claude for a week to see what would happen and ended up being unimpressed with results and saw it massively over complicating simple issues or creating unnecessary liability. All these people are doing is pumping out tons of tech debt and liability that they don’t even have time to digest or understand and for what? Where is the upside or the profit, is it just the reward of seeing line go up in terms of “productivity”. Total madness to me.

I ship 10x that per hour. 369,999 of that are empty lines, then a slick one-liner :)

I wonder if there is a universal limit for speed per lines of code. The one the we think the light has

But HN is still partying like it's 1999... Couldn't he offer a 1/4 day for a HN revamp?
