If he didn't understand the question how could he know the model answered it perfectly?
Would you trust an AI that gets your banking transactions right only 70% of the time?
To give a trivial example, if I take your queen, then recapturing my queen is almost always the single playable move. But it's also a line that you will easily find!
Conversely, in a complex tactical position, (even) multiple saving moves could all be very tricky for a human to calculate.
(Hi probable coworker)
I was having a conversation with a former bandmate. He was talking about a bunch of songs he is working on. He can play guitar, a bit of bass and can sing. That leaves drums. He wants a model where he can upload a demo and it either returns a stem for a drum track or just combines his demo with some drums.
Right now these models are more like slot machines than tools. If you have the money and the time/patience, perhaps you can do something with it. But I am looking forward to when we start getting collaborative, interactive and iterative models.
