My thesis for $IREN & space data centers is that AI compute will be the internet today (In which it is ALREADY). Think about the importance of the internet, people can't function or even work their job without it. The same goes for AI compute. We will eventually 100% rely on some type of AI compute to complete our day to day task in and outside our homes.
AND don't even get me started on the NEED for networking infrastructure. Photonics & connectivity is a HUGE piece.
