There can be too very distinctive and conceptually important beliefs here that seem to be a crux.
Dario doesn’t believe super-intelligence is intrinsically possible given any architecture (Effectively Francois Chollet’s’ view that humans + tools represent something close to the upper bound of intelligence)
Dario believes current architectures at maximum scale and optimization are likely to top out at extremely smart human intelligence (a country of geniuses in a data center), but super intelligence is theoretically possible with a different architecture.
From his comments it seems very difficult to disentangle whether he believes 1 or 2.
It is very easy to believe that he may acknowledge 1. is conceptually possible, but by default he expects 2. given the current state of AI. I tend to lean towards 2. with the caveat that creating a fully automated coder and radically accelerating science may quickly allow iteration super-intelligence via a different architecture (If it doesn’t end the world in a more banal way first)
I work at a threat intelligence company and my default view is that Mythos is likely under-hyped for SWE and overhyped for cyber.
People VASTLY underestimate how easy it is to break into the vast majority of organizations. There is no need to design custom 0-Days because you can simply log-in (or run a session replay attack) using credentials/sessions freely available on the dark web. I would put forward that if Mythos was released tomorrow with standard API guardrails you would not see an explosion in cyberattacks.
However, the one exception is that organizations that already heavily invest in security (think Google) would have a new major attack surface to cover, and you may see an increase in sophisticated actors attacking other sophisticated actors because it changes offense-defense balance in favor of offense.
