Hmm...I didn't understand the comment to be about specific products, so I'd take Glass and Betamax off the list. I really don't think crypto or VR or AR are going to fizzle, I think they're just early in their overall lifecycle. I absolutely think that in ten or twenty years those categories will be much larger than today.
