I remember feeling like a right scientific benefactor running the SETI@Home screensaver on my Pentium II, looking at the fancy graphs. Was it all for nothing?

The fact that all SETI endeavors haven’t really found anything is actually a very valuable result, because it constrains “they’re everywhere, we just haven’t been looking” arguments quite a bit.

Even humanity’s (weak) radio emissions would be detectable from tens of light years away, and stronger emissions from much further. So the idea that intelligent life is absolutely everywhere that was liberally tossed around a few decades ago is pretty much on life support now.

Well it led to the creation of BOINC, a distributed computing system that probably has led to scientific advances in other fields

So I wouldn’t say it was all for nothing, but it’s main benefit was the idea, and not the results it generated

Wait, they have been in hibernation for almost several years, why to publish it now?

It just completed. Published paper. Final release & final analysis: https://iopscience.iop.org/article/10.3847/1538-3881/ade5ab/...

TLDR of jve's AI comment:

You know of this? https://en.wikipedia.org/wiki/Wow!_signal

SETI at Home was a screensaver that was looking for signals like that via distributed searching and they didn't find anything (but they do have telescope time for tackling the 92 highest priority follow-up scans).

Contributing resources to a scientific experiment aligns contributions with outcomes, since getting a hit is knowledge that everyone benefits from: the result (including a negative result) is in the public domain and benefits everyone to know. In this case, the result is that after 20 years of distributed search, no plausible ET signal was found and verified. That's good to know!

I rebuilt my PII system last year and really wanted to run SAH on it for old time's sake but sadly that hasn't been possible for a long time. I miss watching that old screensaver and optimising the system performance so I could get through a WU in less time, iirc at the time it took about 18 hours each.
