maybe because the know we only put pings on a data sheet ?
perhaps thats a the result of lack of energy and free time spent for real data analysis, today and in the past.

Data processing is the main problem of Big Science.

Very true. DA's report from last year said that Seti@Home had no effective back end because Nitpicker never happened. He was negotiating with Einstein to use their Atlas Computing Cluster at Hanover via Nebula. But he is still sorting out the software to analyse the data as we speak, it could be some while yet. Maybe that is why S&H only gets a minimal look in?

The interdisciplinary research on AI applied to SETI should, does and has produced results such as the recent detection of additional FRBs hidden in previously acquired datasets.

Now, if the AI machines of the future (or their owners) tell open democracies when they detect and interpret correctly the next extraterrestrial Encyclopedia Galactica to be received, everything should be hunky-dory.

Perhaps of some use looking for ET?

Many of the big nations in the world are communist dictatorships.

Russia
China
N. Korea
Eastern Europe
Middle east
Africa is mostly petty tyrants

Some would say that even America under Trump isn't that far removed from a dictatorship You do as he says or he'll sack you or throw a childish tantrum. Just how many true democracies where the people get a free vote on matters of public importance, and elect their leaders, are there in the world?

The first country to contact ET and reverse engineer their technology will keep it to themselves (or try to) and use it for military purposes to rule the world.

Dictators

Freedoms

Despite various initiatives like the $100 million Breakthrough listen, most major governments are carrying out their own secret communications, which if successful will not be made public. THe UN is just a talking shop and irrelevant in the 21st C. All we can hope for is that it isn't Russia that finds ET first and ends up with a global country wipe-out super nuke.

Would be good to know if any SETI@Home datasets have, or are going to be, subjected to an AI 'signal agnostic search', as described in one of your links. The AI method is designed to search for any patterns in the noise, with no preconceived ideas about what types of signal we should be looking for.

Defined: how to talk about ET - 12 Dec 2018
SETI Institute expert committee seeks consensus on astrobiology terms, with only limited success

https://arxiv.org/ftp/arxiv/papers/1809/1809.06857.pdf

Whether or not you can hear people scream in space, there’s plenty of screaming, or at least disagreement, about space and the way we describe it. So much so, in fact, that California’s SETI Institute felt the need to convene an Ad Hoc Committee on SETI Nomenclature to make a few decisions on definitions.

The resulting recommendations, which are available online, make interesting reading, starting with what can only be described as a bit of a disclaimer; “This is a consensus document that the committee members all endorse; however, in many cases the individual members have (or have expressed in the past) more nuanced opinions on these terms that are not fully reflected here,” the document says. Then follow nine pages with 24 terms defined, ranging from the simple (alien, intelligence, extraterrestrial) to the complex (Schelling Point, Fermi Paradox, Drake Equation) to the acronym-heavy (CETI, SETA, METI, Active METI, Artifact SETI).
Committee participants: Jason T. Wright, Penn State University Center for Exoplanets and Habitable Worlds and Department of Astronomy &, Astrophysics, PA, USA; Sofia Sheikh, Penn State University Center for Exoplanets and Habitable Worlds and Department of Astronomy & Astrophysics, PA, USA; Iván Almár, Hungarian Academy of Sciences, Budapest, Hungary; Kathryn Denning, Associate Professor, York University Department of Anthropology, Toronto, ON, Canada; Steven Dick, Former NASA Chief Historian and Former Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology and Jill Tarter, Chair Emerita for SETI Research, SETI Institute, Mountain View, CA, USA.

The AI method is designed to search for any patterns in the noise, with no preconceived ideas about what types of signal we should be looking for.
If Dr Siemion's (the director of the Berkeley SETI research center) enthousiasm for cutting-edge data analytics approaches (such as machine learning and AI) is to be trusted, it is just a matter of time before data coming from Green Bank, Arecibo (which partially feed SETI@home) and other sources gets increasingly processed that way, making the alien needles (if they exist at all) in the cosmic haystack easier to find. A question arises: for how much time will classical analytics (such as those used by SETI@home) and machine-learning/AI analytics remain complementary ?

“The kind of searches we do are motivated by what our technology does now,” Dr. Siemion says. “When we invented radio transmitters, we started looking for radio signals. When we invented lasers, we started looking for laser signals. When we invented AI, we started thinking about searching for artificially intelligent life. There’s a deep philosophical relationship, I think, between these two fields.” (...) “We need to make use of as much computing as we possibly can bring to bear on this problem,” he adds.” More recently, that’s been employing some of the modern data analytics approaches coming out of the Valley and bringing that back to SETI – things like machine learning and AI.”

The Seti Institute is just a talking shop, nothing much more. if you like the Seti equivalent of the UN.

The SETI Institute set up in 1984 is a not-for-profit research organization whose mission is to explore, understand, and explain the origin and nature of life in the universe, and to apply the knowledge gained to inspire and guide present and future generations. It aims for discovery and for sharing knowledge as scientific ambassadors to the public, the press, and the government. It collaborates with the Berkeley SETI Research Centre, and partly with Seti@Home.

Expert Committee? Have any of us heard of any one of them?

Technosearch: An Interactive Tool for SETI

Jill Tarter, an all but iconic figure in SETI, has just launched Technosearch, an Internet tool that includes all published SETI searches from 1960 to the present. A co-founder of the SETI Institute well known for her own research as well as her advocacy on behalf of the field, Tarter presents scientists with a way to track and update all SETI searches that have been conducted, allowing users to submit their own searches and keep the database current.
