Did Carl Sagan doom the Earth,...

and they would have to triangulate to find us, thats true. If youre thinking about radio astronomy, thats because of the vast distances were talking about - remember that were talking about speed here. The probes wont get anywhere particularly interesting for thousands of years. And yet our EM emissions have covered many lightyears already.......
... by sending 2 beacons into outer space describing all of our weaknesses, and precise location?

-
yes and now what we should do is send out a bunch more with nuclear bombs and booby trapped doors

-
Nah.

They're just now passing into interstellar space. We've got plenty of time before it can reach anywhere where they wouldn't have homed in on us anyways because of EM radiation, such as our radio and TV signals.

EDIT:
No, you're wrong. EM signals are quite omnidirectional. Sure, they get attenuated over distance, and they would have to triangulate to find us, that's true. If you're thinking about radio astronomy, that's because of the vast distances we're talking about - remember that we're talking about speed here. The probes won't get anywhere particularly interesting for thousands of years. And yet our EM emissions have covered many lightyears already.

To sum it up, any civilization that would have the technology to pick up our probes in interstellar space would also have had more than enough sensor technology to find us through our EM radiation simply because of the vast speed differential between EM radiation and the probes, and would have had much more TIME to look for us using EM radiation as well. I therefore completely disagree with your statement "it may be more likely that the probes give us away".

Also, not to mention that in 40 000 years' time, there won't necessarily BE "human beings" even. Evolution is still ongoing - it's more or less just the orangutan that has been essentially unchanged over 40 000 years (and even they are picking up their rate of genetic change).

1. Who told you Carl Sagan launched anything?
2. If you're talking about the Voyagers, have you any idea of the odds
against anybody ever even noticing objects that small?

-
They have to be found first and second, their nuclear power supplies are just about dead.
Oh and third, we humans can only assume that if the probes are found, that the instructions inscribed on them can be deciphered.

Anyway, the bloke in that picture looks like you don't want to mess with him.
