You completely missed the point of bitcoin mining. The energy expenditure is the main factor that keeps the network secure.

ASICS get more efficient all the time and hashrate keeps going up because of it, but the thing that should be looked at is energy expenditure. That's the real cost of network security.

So, if someone could figure out some big leap that reduced the energy expenditure, then that could reduce network security?

Efficiency improvements have been happening the whole time and energy expenditure isn't going down.

Why do you think that is?

Asking this question reveals the lack of understanding about the topic.

If somebody invented an ASIC that is so powerful that just one machine replaces the entire current hashrate, what do you think will happen?

Will everybody except that one guy with that one ASIC just stop mining and leave OR will they try to get a few of those as well?

The limiting factor, in todays world, is energy.

This person gets it. And that energy is Electricity in particular. And electrical power works within parameters of current, voltage, and resistance, within conductors for transmission like copper or aluminum. These create physical restraints to delivering electricity to where it’s needed, further expanding the limitations of todays world for bitcoin mining.
