I don't understand how Meta could be a compelling game changer like the iPhone because I don't understand what practical value it offers. The iPhone and mobile in general has had an incredible impact on economic efficiency alone, much less the cultural changes it has driven. People can't live without their phones. Whether or not that's a good thing is TBD, but it's hard to imagine a product that is similarly indispensable - Automobiles maybe? Electricity? Indoor plumbing? Ok, so then compare Meta's big idea. Standing in a room with a screen strapped to your head, blocking out the rest of the world and rendering your body useless? What exactly is that going to provide other than an enhanced gaming or entertainment experience? I fully suspect that I'm missing something because it seems ridiculous. Not the idea of an immersive experience to enhance entertainment, but the idea of taking the largest social media portfolio of companies and pivoting towards this. For context, I get metaverses. I was a pretty big participant in SL from 2006-2010ish. I wrote tons of lsl and collaborated with builders to sell 10s of thousands of dollars of silly things that made people's experience more fun. So as a fun side thing, I get. But how exactly could that translate in to THE thing? Especially if it means sitting like a zombie on my couch?
