jtgi··on Domain expertise has always been the real moat
> 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.

jtgi··on The Web3 Fraud
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.

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