With cybersecurity, it might be "defense dominant" in the sense that we can eventually patch all of our systems to be robust to hacking from even the strongest AI agents. Although it may get worse before it gets better. In a defense dominant world, widespread access to powerful AI could be fine.

However, other areas of risk such as biosecurity may be "offense dominant". For example, we cannot exactly patch the human immune system to defend against artificial viruses the same way that we can patch computer systems.
