Concidentially, today I was watching and interview with a lead designer from Ramp who is telling about how they are full ia, agents and automation https://youtu.be/KPDXMtmkcgk
I’ll believe in AI agent’s abilities the day two criteria can be met.
1. A killer app is made with it.
2. That app doesn’t rely on heavily subsidized models that are burning a dollar to make 20 cents.
FWIW I agree with your criteria for AI agent success, and I haven't seen it happen yet.
