I wish everyone in this space well, and huge funding rounds can be a huge weight dragging a company down, but I feel like Meta is severely undercapitalized to be in this market.

Microsoft doesn't have a tethered product right now, but it seems very likely that an OEM will[0] and Microsoft will help them build it and will provide the software - somewhere that Meta 2 has been struggling with.
