If o3 can design it, that means it’s using open source schedulers as reference. Did you think about opening up a few open source projects to see how they were doing things in those two weeks you were designing?
We looked at the existing solutions, and concluded that customizing them to meet all our requirements would be a giant effort.
Meanwhile I fed the requirement doc into Claude Sonnet, and with about 3 days of prompting and debugging we had a bespoke solution that did exactly what we needed.
The only real complexity in software is describing it. There is no evidence that the tools are going to ever help with that. Maybe some kind of device attached directly to the brain that can sidestep the parts that get in the way, but that is assuming some part of the brain is more efficient than it seems through the pathways we experience it through. It could also be that the brain is just fatally flawed.
