If we have a Kurzweil-style intelligence explosion, the next 200 years might actually be significant even to much older civilizations. If there's "no stealth in space" then a dark forest is impossible anyway. If a dark forest is possible, then it's possible for humans to go dark as well. Generally, how much stealth is possible depends on how far away the adversary is. Usually people are talking about interplanetary distances when they say that, rather than interstellar.
