> I will just point out the benefit is not as obvious as you think. Developers have consistently overestimated LLM I think there are two different claims here: - developers overestimate productivity gains, which is a solid finding in many of these studies. Skepticism of extremely large productivity gains is warranted and I flatly disbelieve "10x uplift" claims. - LLMs give no productivity uplift at all, which is much…
Maybe we can make an analogy with taking the plane vs driving to your destination. A plane literally goes 10x faster than a car, so a 5 hour drive becomes a 30 minutes flight. But if you have to drive to the airport, arrive early, pass check-in, security, boarding, then pick up your luggage on arrival, rent a car and drive to your destination, you may realize that your 30 minute flight took you more than 5 hours in t…
It's a 10% speedup, unless you think that a 100% speedup would reduce completion time to zero rather than cutting it in half.
Assuming that "10% of the project" is measured by time requirements, when you get a 10x speedup on that part of the project, you'll end up completing 100 units of work in 91 (formerly 100) units of time. Your work rate is then 100 / 91 = 1.099 times what it was before; that's an improvement of 10%, not 9%.
(Sanity check: suppose you have a project that will take 100 days. That project is reassigned to someone 10% faster than you. They will take 100 / 1.1 = 90.91 days to finish.
If they were 9% faster, they'd take 100 / 1.09 = 91.74 days to finish.
Does a savings of 9 out of 100 days of work look more like the project that saves 9.09 days, or the one that saves 8.26 days?)
