What about Google? They realised years ago that the market doesn't really want their product and found other niches to build their glasses for. If it's so obvious why would Google not care and only meta (which has a bad track record in finding trends) and apple follow that 'trend'
Google isnt much of an innovator they will just copy or steal from the market leader who finally gets it right like they did with Android and like many of their other products ..Siri first then Google assistant ...Alexa smart speaker then Google home products and etc, etc, etc
