Business lesson, : never build a factory because it won't pay for itself in the first year.
And yes I know it's hard to hear but Meta's vr is doing really well in the areas they targeted, industry, academia, and special use. This is likely to end up a profitable part of their business for a long time.
Yeah unfortunately I agree, as much as I dread knowing Meta's going to be behind a lot of the VR/AR developments as it gets more common, this isn't really an indication that they screwed up. They're not the first company I'd want to lead the VR market but it looks like they will be regardless.
