> It's expensive (but not really, only compared to knives - a $500 GPU isn't expensive).

No, it's really expensive. $400 is nearly a week's pay for an hourly worker in much of the US. For many on this site it might be less than a day's labor but that's not the general case.

The lack of trust is probably because knives seem to be a favorite product of shysters. Selling expensive knives that promise the moon and wow the audience with cool knife tricks just reeks of fast talking late-night infomercial salesman trying to get over on grandma. The tech looks cool, but the presentation is off-putting.
