I think there are many reasons some but not all imo:

- The price difference. Calling a person who dropped $1,500 on a "tech glasses" in 2013 a glasshole made sense. It felt like someone with more money than sense. Meta glasses are $299 today that's just small gadget money so there is no "too much money, little sense" aspect

- Tech went 100% mainstream. It wasn't exactly an exclusively nerdy or geeky thing in 2013 anymore like the 90s or early 2000s, but there was still certain "Too much tech means you are a socially incompetent neckbeard". Today the biggest socialites online often do a tech haul style videos about the latest tech gadgets they got.

- Cameras exploded everywhere. Everyone has watched footage from Ring, GoPro, traffic lights, security cams, court cams, dashcams, police body cams, etc. Plenty of regular people got home cameras too and find it very useful to keep an eye on pets, backyards, etc. Plenty of very regular people have stories about how their cameras saved their ass in one occasion or another. There has been plenty of high-profile news stories about how a Tesla or a Ring camera helped solve a crime or catch a horrific murder or criminal.

- The proliferation of prank YouTubers in the 2010s. Even though most of them were paid actors, going out and acting as a douch and recording it became a mainstream. Kids love it, and despite the "backlash" they were getting millions regardless

- It doesn't matter how you feel about meta glasses or google glasses, you will have reports online of people who tell you how those products changed their life for the better because it helped them overcome some adversity, or protected them in a victim situation or literally saved their life in some situation
