from reddit r/ExperiencedDevs • 21h ago Tech-Cowboy An AI CEO finally said something honest (Meta Dax Raad from anoma.ly might be the only CEO speaking honestly about Al right now. His most recent take: "everyone's talking about their teams like they were at the peak of efficiency and bottlenecked by ability to produce code here's what things actually look like - your org rarely has good ideas. ideas being expensive to implement was actually helping - majority of workers have no reason to be super motivated, they want to do their 9-5 and get back to their life - they're not using Al to be 10x more effective they're using it to churn out their tasks with less energy spend - the 2 people on your team that actually tried are now flattened by the slop code everyone is producing, they will quit soon - even when you produce work faster you're still bottlenecked by bureaucracy and the dozen other realities of shipping something real - your CFO is like what do you mean each engineer now costs $2000 extra per month in LLM bills"
someone in AI fucked up and actually told the truth
