I'm not the poster you're replying to, but I think you've missed their point here.
Market penetration of mobile phones was (initially) driven by the advantages they provided as a work tool. This growing market that was willing to pay helped drive the cost vs. utility down to the point where non-business use cases became viable.
Goggles with screens in them have had a very different history. There are exceedingly few people/careers who have gotten a good ROI from buying and using a headset, so most sales are driven by entertainment (and a small number of enthusiasts).
Apple (and Meta) can definitely continue to subsidize the development of this technology to bring the price down, but expanding from a niche market for entertainment devices to a market of professional tools is the opposite of what's worked for new technologies in the past.
