More likely just not seen yet, our furthest reaching signals are maybe 50 light years away at best... and that's if anyone's looking for the faintest of faint traces.
The Milky Way is 100,000 light years in diameter.
So don't worry, maybe someone will blip us out of existence someday.

This is the key. On interstellar scales, things move very, very slowly and you have to plan on time scales measured in millennia. IMHO we are doomed simply because we can barely think beyond the next election cycle. (At least that's true for Americans. The Chinese seem to think in terms of decades and, occasionally, centuries.)
