Their goal is to bring about Artificial General Intelligence (AGI). Basically sci-fi level AI that is genuinely capable of independent thought with superhuman processing speeds.
Something on the order of 10,000 years worth of effective personal time for every 24 hours of real time.
Think about what an entity capable of experiencing 10,000 years worth of time every 24 hours would be capable of after just 15 minutes. We would just hand over every single human job to the AI and then I don’t know go have fun for the rest of time. Theoretically every problem that comes about could be resolved by the AI.
Cure for every disease, every logistics problem resolved, every possible technology invented instantly.
