Taking these in order:

>Agreed, but last I checked, any detection is happening way to late to do anything with current technology.

Simply not true; big ones are spotted and plotted years in advance, plenty of time to mount missions to deal with them.

>My thoughts are that, if we were truly motivated by the 'life or death' nature of a potential impact as some here implied (I disagree with this reasoning)

You disagree that a large asteroid would be an extinction level event? The one that wiped out the dinosaurs was a bit more than 6 miles in diameter- and it would do the same to humanity.

Apophis, the one that blew by here a few years ago, was discovered in 2004. Its diameter is only 600' but we know it comes close to Earth occasionally. If the probability of impact were high, we definitely would put together a mission to meet it...

>efforts would be going into means of stopping them (we have pretty much none), rather than detection.

..which leads to my last points; first, we have to detect them to know they're coming. Hell, we want to know about every chunk of rock flying around the solar system just because!

Second, between large boosters to get heavy payloads into orbit, high yield nuclear weapons, and precision guidance of the kind demonstrated by NASA's recent impactor mission, we definitely have the capability to do the job. It's a question of will, that's all.

The bigger they are, the easier it is to see them at greater distances, which makes it easier to do something to alter their trajectory because the farther away we intercept them, the less energy is needed to move them off course.

If your life depended on counting change, you would have incentive to get it right

When asteroids are coming this close to earth, they really want to make sure of the trajectory, in case of impact.

If it's true AGI that's smarter than humanity, we won't know until it's too late.

I find that possibility to be remote because it would have to know all of our capabilities and how could it know that?
