Sure, those wearables may find niche use cases, but Zuckerberg definitely believed that the "Metaverse" (god I hate that term) would be the Next Big Computing Platform, as significant as the switch from desktops and laptops to smartphones. That has certainly not happened, and lots of people, myself included, still feel that all of these other devices are at best a "oh, that's cool" for a bit before ending up in a drawer somewhere, or at worst an undesired annoyance.
It should be a lesson in doing the opposite to /r/stocks sentiment. (They also had tons of posts on why shorting nvidia would be a great idea a year ago).
Basically do the opposite to the most uneducated group of investors you can find and you have a good chance at making money off their bad trades. Don’t try to inverse the large firms with huge amount of research. Just inverse reddit for easy money.
