I'm not totally sure he's "on the fence."
I think he's asking the right questions - and he could actually be asking those questions while at the same time personally and/or professionally doubling down on these technologies.
I see analogies to questioning one's religion: I'm a Christian, but I don't have all the answers and I do keep asking the why behind a variety of doctrinal and existential questions. Doesn't make me any less of a Christian, and, in the long run, actually helps strengthen my faith.
But, like anything else, I could be wrong.
And, in Christianity as in blockchains, asking "why" will invite accusations of apostasy from some corners. :)
Plus, it almost always leads to no good answers and no progress for anyone. That took me quite awhile to learn.
The honest truth is, you can defeat almost any illogical argument (speaking hypothetically here) by just asking "why" over and over, until eventually the other person will simply end up giving you their fallacy, rationalization, or "feelings based justification", conceding the argument. It, uh, doesn't exactly win them over though, although you may captivate the hearts and minds of onlookers.
The truth is we are very ego-invested in our opinions, and when we run out of legitimate logical (or illogical) defenses, we will play the race/apostate/no-true-Scottsman card to protect ourselves from cognitive dissonance.
Yup.
Good point
