If this was a mining situation, then yes, it would be dumb.

Is that what this is actually doing though? Is it PoW for a mining operation, or just causing some electrons to be moved around to prove your not a bot? I didn't read too far into what the PoW actually is since their demo shat the bed.

The problem is spam networks have more computers and more power than your phone does so any proof that you can do, spammers can do 1000x faster. PoW can sort of work when your attack to defend against is a ddos situation where an attacker has to make far more requests than the average user, but most captchas try to defend against bots being able to use the site at all which PoW can not do.

how does doing computation without human interaction prove you're not a bot? It only proves you're running a browser with javascript enabled on average hardware.
