If you take a step back, the vision is easy to get behind - of course, it'd be much better to augment reality with digital artifacts instead of staring into 5-inch phones. Of course! And the company that invents it would herald a significant platform shift and can benefit immensely, as Apple has from smartphones. The challenges are mainly capital for R&D and technical feasibility, which Meta has realized through many iterations.
It is better to follow difficult but obviously true and impactful visions, than easy but low-conviction pursuits. But it takes an extraordinary amount of risk tolerance, grit, and execution prowess to pull it off. Kudos to Zuck for pursuing such a vision, and persisting.
Notes:
1. Pun intended!
2. Just bought some Meta stock.
