One way to characterize intelligence is the capability of solving problems one has not specifically been trained for. Somebody who has trained painting animals and vehicles for decades is surely skilled at that, but is not solving new problems, so is not necessarily applying intelligence when painting something of that sort. You can take a reasonably skilled programmer, show them some C code and ask them to write equivalent ASM code, perhaps providing them with a language reference for either, and they will be able to do this translation. Slowly, but they will get there. They have not been trained to do this, but they will "figure it out". With enough time and motivation, even non-programmers would be able to do that. That is what intelligence is and of course Claude/GPT needs to be able to do that if it wants to claim that it intelligent. No flying horses.
