> Agentic AI severed the link between the two. You can now produce the software without ever building the model, and that breaks an assumption the whole profession was organized around.

Nah, we’ve always produced software without much understanding of the domain. It’s the premise behind lean: we don’t know much, so get something in front of customers and refine it.

So I don’t believe there’s been a strong decoupling here akin to the degree that understanding the code and writing the code has been.

api can return “http 402 payment required” and clients can include a signed payment. nice for agents.

New comment by jtgi in "Automation enables founders to grow companies with fewer and fewer employees"

No, negating “employees created all the value” does not mean, “founders create all the value”. It means employees didn’t.

Every architecture makes trade offs.

Creatively showing how expensive and slow Ethereum is is entertaining but not entirely relevant. It's like comparing a passenger airplane and a tank, claiming transportation is their sole purpose and since airplanes are both faster and cheaper than tanks, tanks are fraudulent.

Ethereum is architected to be a decentralized, permissionless computing platform. Performance is one of the trade offs.

It's much more productive, and more challenging in my opinion, to discuss whether or not the trade offs being made are worthwhile.

thought you were going to say you teach functional basics like map, filter, reduce, etc. converting between recursive/iterative is a good exercise but teaching one and not the other seems unnecessary, especially considering you see more loops in the wild. --- also fwiw can just ``` highlightProducts(aListOfProducts.splice(-5)) ```

Ask HN: Have you ever been contacted to sell your user's information?

jtgi — Mon, 06 Jul 2015 01:05:31 +0000

My friend who runs a student service with a couple thousand users was contacted today over Facebook with an offer for his user's emails:

"It's for an event newsletter. Won't say we got it from you."

This ask really bothered me, both from an ethics and pragmatic standpoint. Which got me thinking about the scandals and pressure larger companies, especially ones that are failing or have failed encounter with their user data. At non trivial quantities or certain domains this data must get extremely valuable. Combine this with the increasing likelihood that developers have access to production services and I was left feeling a little uneasy.

Have you ever been contacted as an employee/founder with an offer for your user's data?

What happens to user's data when companies die? Is it purged, sold off, dormant?
