There's much more to amateur radio than just operating - at least over this

I first heard of cognitive radio systems when efforts were underway to make
use of the 'white space' in the television broadcast bands. The whole idea
is to make more efficient use the the spectrum by putting situational
awareness in to the client device.
Same here. I do not operate digital modes at all personally, even those
I helped to create and/or improve. I operate 160m and 40m CW almost
exclusively. That does not stop me from conducting experiments, doing
design work, and using the brain I was given to learn and expand

I doubt whether amateur radio has ever been more alive than it is at

So long as vanity repeaters are put up by people who are willing to
become litigious, this is a war that will have MANY casualties. We are
not the government (anywhere in the world, not just US) and have the
right of eminent domain over spectrum, property, etc.

One problem with cognitive radio is that it seems it will be designed

Therefore, it is best used in spectrum particularly allotted to
just those kinds of emissions. This rather defeats the
