I'm sure that explains some of it but I really don't think it explains most of the people who have been AI-pilled in the last nine months. There was no amount of context I could give GPT-4o that would make it a net benefit to use that for agentic development. I tried it with quite sophisticated prompt systems and much simpler ones, compendiums of code & business analysis and sparser ones. Yet it just wasted my time - still there were people using Cursor with that model and saying it was life changing. I didn't have that experience until Opus 4.5 - its possible I could have had it earlier but that was when I happened to try it again.
