More like 2 if you look for modern humans in the fossil record. I accept it's a very small chance of success, but that won't matter if we keep doing it, the software will improve over time and more things can be added to look for. I don't run any seti stuff no more because Boinc kept crashing my machines, will the old setup's still work? Love Seti,

Many hundreds of thousands of years?

I accept it’s a very small chance of success, but that won’t matter if we keep doing it, the software will improve over time and more things can be added to look for.

I don’t run any seti stuff no more because Boinc kept crashing my machines, will the old setup’s still work?

I know you can turn down the amount of resources you can use, but that sort of defeats the purpose right? Also, for some reason the old screensaver, with 2D gfx looked better/cooler/techier than the 3D thing you got going on now.

When they released the new BOINC version, at the time it seemed to eat a bit too many resources, and shortly after downgraded. Overall it's a great concept, but I am conflicted about the ethics regarding the energy usage of machines that aren't being used. Technically, if you're not using the machine, it probably would be best for our electrical bills and carbon footprint to turn the computer off.

SETI is cool, but I honestly believe that protein folding is a more important task.

Consider that human beings have been transmitting radio signals for little over a hundred years, but there has been intelligent life on Earth for many hundreds of thousands of years beforehand. SETI would be useless to discover such a planet. In my opinion SETI is fundmentally flawed, and extremely unlikely to find anything, especially considering the time it takes signals to travel through the expanses of space. If SETI _did_ hear anything, it would most likely be from a source that has long since passed. SETI may have reasonable funds and large-scale amateur support, but it's essentially little more than an expensive gamble. I really don't think it deserves the pride of place on this site that it has been given, especially when compared to some of the other content.
