We have both been using or integrating AI code support tools since they became available and both writing code (usually Python) for 20+ years.
We both agree that windsurf + claude is our default IDE/Env now on. We also agree that for all future projects we think we can likely cut the number of engineers needed by 1/3rd.
Based on what I’ve been using for the last year professionally (copilot) and on the side, I’m confident I could build faster, better and with less effort with 5 engineers and AI tools as with 10 or 15. Also communication overhead reduces by 3x which prevents slowdowns.
So if I have a HA 5 layer stack application (fe, be, analytics, train/inference, networking/data mgt) with IPCs between them, instead of one senior and two juniors per process for a total of 15 people, I only need the 5 mid-seniors now.
