The "Master of Doom" leaves Meta, taking with it much of the remaining credibility of Mark Zuckerberg's metaverse.

According to the title, John Carmack was only employed in an advisory capacity at Reality Labs, but was considered the figurehead of Meta's VR division.

In his statement, he praised the successes of the past ten years.

Nevertheless, his verdict on the company is devastating: If Meta were a graphics card, it would only run at 5 percent utilization.

Said chips are expensive and consume a lot of energy.

This also applies to a company that can easily lay off 11,000 employees and has no difficulties with business activities.

While he's only a source, Carmack's suicide note reinforces the impression where Reality Labs' $9.4 billion loss in the first nine months of the year went: Into a bottomless pit.

In the end, Zuckerberg may be right about his bet on virtual reality.

But if he doesn't streamline his company, the competition on the field will soon overtake him.
