Mostly. This is because, theoretically, we could still save the ISS and move it into higher orbit. NASA has calculated that propelling the station more than 640 kilometers above Earth would keep it alive for 100 years—and also require at least 18.9 metric tons of propellant. That’s roughly 2,000 airline carry-ons. A thousand years would require at least 36 metric tons. If that doesn’t seem like very much, consider the fact that, right now, no vehicle can transport that amount of gas to the station. The still-in-development SpaceX megarocket Starship might be able to haul a significant percentage, but it would struggle to dock with the station, according to the space agency’s estimations.
AI should remove friction, not permanently raise the biological ceiling. It should expand strategic capacity, not compress recovery time. Metrics can discipline performance, but they cannot eliminate physiological constraints.

Finally, CPU 0 releases the lock. It sees that its node has a next pointer set, so it knows that there is another waiter behind it in the queue, in this case CPU 3. It sets the locked flag of the next waiter to 0, thus making the next waiter the new lock holder and breaking out of its spinloop:
