Greenfield != boilerplate and basic CRUD app.
I'm a consultant writing greenfield apps solo, and 90% of my time is spent away from my editor thinking, planning, designing, meeting with stakeholders. I see no benefit in using a low-IQ autocomplete tool to automate a small part of the remaining 10% of the job, the easiest and most enjoyable part in fact.
Personally I find most of coding I do is unsuitable for LLMs anyway, because I don't need them to regurgitate standard logic when libraries are available, so most of that 10% is writing business logic tailored for the program/client.
Call me elitist (I don't care) but LLMs are mostly useful to two kinds of people: inexperienced developers, and those that think that hard problems are solved with more code. After almost two decades writing software, I find I need fewer and fewer code to ship a new project, most of my worth is thinking hard away from a keyboard. I really don't see the use of a machine that egregiously and happily writes a ton of code. Less is more, and I appreciate programming-as-an-art rather than being a code monkey paid by the line of code I commit.
Disclaimer: I am anti-LLM by choice so my bias is opposite than most of HN.
