LLMs are often trained on up to some 80% code, depending on use although usually it’s probably lower, as that has been shown to improve their logical/thinking skills.

Basically, if the task can be done with only words and there is a lot of data of it present day LLMs can probably get really good at it if properly trained for it, but for things like circuits, where a lot of the data is likelly to be graphical or there might just not be much of it, LLMs aren’t yet as good at.

Another point that I don’t hear about is that even if Ukraine decided by their own will to join the “destroy Russia” club then Russia would be very much in their right to do something to avoid that from happening. Although, what really happened is that Ukraine was couped and made to do that, so from that point of view I would say that Russia not going directly against the ones responsible was not the “best” they could have done to put a stop to the situation but it was the easiest thing they could do so they are doing it.
