I agree. So, "you" in that passage refers to all believers at that time and ever since then to be ready for Jesus's return, right? I see Matthew 24:6 similarly.
Matthew 24:6 You will hear of wars and rumors of wars, but see to it that you are not alarmed. Such things must happen, but the end is still to come.
The necessity to understand that wars and rumors of wars, along with the other things Jesus mentioned like famines and earthquakes, would not indicate that the end was at hand yet, is something for all believers, and not just the disciples, to understand. That would not be the case if those things were the beginning signs of the coming destruction of Jerusalem in 70 AD, but it would be the case if that is in relation to the future coming of Christ, as I believe.
