Am I crazy or is copper becoming one of the most obvious AI investments?

Every day I see people arguing about NVIDIA, AMD, OpenAI, etc. But the more I read about AI infrastructure, the more I keep coming back to copper. All these data centers need power. All that power needs transmission lines. All those transmission lines need copper.

Meanwhile I keep hearing that new copper discoveries aren't exactly keeping up with future demand. Maybe I'm missing something, but it feels like everyone wants exposure to AI while ignoring the stuff that actually makes AI possible. Anyone else looking at copper or am I connecting dots that aren't really there?
