Joby's Electric Air Taxi Flew Over Manhattan. Passengers Are Years Away.
Joby pulled off a splashy Manhattan demo, but FAA certification and the hard economics of eVTOL still stand between the company and fare-paying riders.
A growing faction of AI researchers is making a pointed argument: the only intellectually honest way to use a large language model for serious research is to trap it inside a closed-loop knowledge base where every answer must trace to a document you put there. No freelancing, no training data the model can't show its work on, no hallucinations dressed up as citations. Andrej Karpathy has championed the idea, and tools like Recall are building products around it.
The argument lands hardest in fields where being wrong has consequences — law, medicine, academic research, financial analysis. In those contexts, a model that occasionally invents a plausible-sounding source isn't a productivity tool, it's a liability. A closed-loop system that only knows what you fed it, and says so when it doesn't know, is a different product category entirely.
If the pattern scales, it fragments the "one giant chatbot for everything" model that OpenAI and Google have built their consumer businesses around. The question is whether users will pay for the discipline of bounded knowledge, or whether the convenience of the general-purpose assistant wins regardless of its accuracy. The research community is betting on discipline. The market hasn't decided yet.

As AI agents move money, send emails, and approve workflows, vendors, deployers, and users are all pointing at each other on liability.
A viral post argues the biggest productivity wins come from stable workflows around any good-enough model — not from upgrading every time benchmarks shift.
