Judging by what I've seen recently, 100% LLM code is often buggy and not that great. I'd say code quality truly matters in all domains
In my opinion nearly the opposite is true: modern business solves for the "minimum viable quality". What is the absolute lowest quality the software can be and not tank the business.
It does. The degree may not, though.
"We have a threshold of at least 5 hours total uptime every 24 hours" is still a quality bar, even if it is different to "We have a threshold of 99.99% uptime per year".
