I've wondered the same thing, at times. There is already evidence that AI is forcing it's will down our throats. Case and point, Autocorrect!! At any rate, at least we'll have Del Spooner.
There have been movies about this and even the occasional "expert" warning us of this since the 1950s. I'm not going to spend any energy worrying about it.
If its a ccw state, or a stand your ground state, the 30 year old might not want to take a beating and pull a pistol and be legally fine.
Given that neither "typical" person of that age has any experience street fighting ... I would put money on the 30-year-old.
Why? Because he has more life experience, and would be more likely to fight "dirty".
