COVID is of course a scourge, but it's not the only one we're facing.
It would sure be nice to find a prevention for drug addiction.
One can be addicted to things other than drugs. Addiction can be physical & mental. Gambling, sexual, shopping are mental disorders when done excessively. How does one discover if one has an addictive personality? I suppose as we now can look at the brain while it is reactive to these behaviors we could run tests. I have always been able to quit behaviors without a problem. Highly disciplined & cautious am I. Others are trying to subvert mental anguish thru artificial means. We have so many epidemics that some would just prefer to tear things down than find a solution to the problem. Finding an answer to drug addiction would be a positive method of addressing this issue, as the "war on drugs" has failed miserably with consequences impacting the entire world.
I am somewhat compulsive myself. I have no doubt that part of the reason I've avoided drug and alcohol problems is that I'm twisted enough that I cannot surrender control like that (as if of course I don't have plenty of other issues instead. Ha, ha.).
Semantics can be played at multiple levels.
There are lots of questions. And at best I doubt they would be able to do more than create a tool that works on some things, some of the time.
Personally i hope it could add to our understanding of various processes and help some people along the way.
