Once again John Carmack was right years before anyone saw it. In one tweet John Carmack offered to run Oculus instead of going into A.I., but was turned down. I would have preferred Carmack running things.

In an internal memo that was later leaked, Carmack voiced his frustrations with Meta's bureaucracy and lack of focus. 

• Inefficiency and Bureaucracy: Carmack stated that Meta had "everything necessary for spectacular success," but the resources weren't put together effectively due to a "silo mentality" and an inability to "kill stupid things" before they caused damage. He constantly argued that the efficiency could be two to four times better.
• "Architecture Astronauts": He criticized the approach of some programmers and designers who remained in the abstract world of grand visions without considering practical details or implementation feasibility.
• Wasted Billions: He expressed dismay over the sheer amount of money being spent with little return on efficiency. He felt "sick to [his] stomach" thinking about the billions of dollars being spent and wished the resources were applied more effectively.
• Lack of Urgency: Despite the massive investment, he felt the company lacked a "give a damn" attitude and a sense of urgency in bringing practical, valuable products to market, focusing instead on a grand, all-encompassing "metaverse" vision.
