It doesn't lead to a more secure network because the costs to attack the network are the same. Attackers will have access to the same technology and have similar costs.

Right, I'm not saying there will be a new ASIC; just that there will be no innovation in the Bitcoin space (unless they switch out of PoW) that leads to less energy being used.

I agree with that, it seems very unlikely we'll go to a less energy situation unless a price decline happens. At least until all bitcoins have been dug out.
