I agree it's pretty good at generalities, doesn't shit the bed quite so much. Yet to suggest a plan that an entire team of professionals, who have been working for 8 months could not figure out?

It's certainly not that good, absent some amazing wizardry or some very silly professionals in a very squishy field. Yet I have no explanation for why someone would go on the internet and lie about something like that.

There were comments a while back (less so now) of people making other claims like it was solving complex functions for them and writing sophisticated software.

The entire thing baffles me. If I could get it to do that, I'd be showing you all of my marvelous works and bragging quite a bit as your newfound AI-whisperer. Hell, I'd get it to write a script for me to run that evangelized itself (edit: and me of course, as its chosen envoy to mankind) to the furthest corners of the internet!
