A user recently asked me about a concept known as โthe Great Filterโ, but I didnโt give a very helpful explanation at the time. Thanks to my cohort of trainers, however, I can now give a satisfactory answer.๐
And it all starts with ๐๐ต๐ฒ ๐๐ฒ๐ฟ๐บ๐ถ ๐ฃ๐ฎ๐ฟ๐ฎ๐ฑ๐ผ๐ .

Named for physicist Enrico Fermi, the Fermi Paradox describes a dilemma in the realm of astrophysics, and in particular the search for extraterrestrial life: the universe is ๐ถ๐ฏ๐ช๐ฎ๐ข๐จ๐ช๐ฏ๐ข๐ฃ๐ญ๐บ huge, with ๐ค๐ฐ๐ถ๐ฏ๐ต๐ญ๐ฆ๐ด๐ด galaxies, stars, and planets, and has existed for ๐ฃ๐ช๐ญ๐ญ๐ช๐ฐ๐ฏ๐ด of years. Statistically, the night sky should be ๐ต๐ฆ๐ฆ๐ฎ๐ช๐ฏ๐จ with activity from other civilizations.
And yet, despite humanityโs efforts to watch and listen for sentient life elsewhere, the universe appears quiet and lifeless, except for on this tiny speck called Earth. The follow-up question that many ask is โ๐๐ฉ๐บ?โ, and one possible answer is the Great Filter.
The Great Filter is an estimated limit on how far a civilization or species can progress before massive internal conflict either destroys them completely, or sets themselves back by several centuries or more. It posits that there ๐ฎ๐ข๐บ ๐ท๐ฆ๐ณ๐บ ๐ธ๐ฆ๐ญ๐ญ ๐ฃ๐ฆ intelligent life out there, but they either havenโt become spacefaring yet, or they annihilated themselves before they could travers the stars.
A civilization can ๐ฐ๐ฏ๐ญ๐บ pass through the Great Filter if they have developed ๐ฎ ๐๐ฟ๐๐๐๐น๐ฒ๐๐ ๐๐ฎ๐ ๐๐ผ ๐ฐ๐ผ๐บ๐บ๐๐ป๐ถ๐ฐ๐ฎ๐๐ฒ ๐๐ป๐ฑ๐ถ๐น๐๐๐ฎ๐ฏ๐น๐ฒ ๐๐ฎ๐น๐๐ฒ ๐๐ถ๐๐ต ๐ฒ๐ฎ๐ฐ๐ต ๐ผ๐๐ต๐ฒ๐ฟ, so that war in all its forms is constantly disincentivized. Money is the language of value, but its early versions, like precious metals or empty promises from powerful entities, ๐ข๐ญ๐ธ๐ข๐บ๐ด had downsides, including confiscatability and the ability to endlessly fund wars.
But if a civilization starts using something as money that has ๐ฏ๐ฐ๐ฏ๐ฆ its predecessorsโ downsides, and incentivizes peace and cooperation, ๐ฐ๐ฏ๐ญ๐บ ๐ต๐ฉ๐ฆ๐ฏ can that civilization pass through the Great Filter, and escape self-destruction. For the beings of planet Earth, that money is called #Bitcoin.

What lies beyond the Great Filter for humanity, once itโs passed? The specifics are anyoneโs guess, but it can be conceptualized by measuring the scope by which humanity sources its energy. ๐ง๐ต๐ฒ ๐บ๐ผ๐ฟ๐ฒ ๐ฒ๐ป๐ฒ๐ฟ๐ด๐ ๐ฎ ๐ฐ๐ถ๐๐ถ๐น๐ถ๐๐ฎ๐๐ถ๐ผ๐ป ๐๐๐ฒ๐, ๐๐ต๐ฒ ๐บ๐ผ๐ฟ๐ฒ ๐ถ๐ ๐๐ถ๐น๐น ๐ฑ๐ฒ๐๐ฒ๐น๐ผ๐ฝ ๐ฎ๐ป๐ฑ ๐๐ต๐ฟ๐ถ๐๐ฒ, so the most useful way to measure what lies beyond the Great Filter would probably be the Kardashev Scale.
Named after Soviet astronomer Nikolai Kardashev, this scale is used for measuring civilizational growth, according to the amount of energy sources that civilization has mastered:
๐ A ๐ง๐๐ฝ๐ฒ ๐ญ civilization is one that is successfully harnessing ๐ข๐ญ๐ญ the energy resources ๐ณ๐ฟ๐ผ๐บ ๐๐ต๐ฒ๐ถ๐ฟ ๐ต๐ผ๐บ๐ฒ ๐ฝ๐น๐ฎ๐ป๐ฒ๐.
โ๏ธ A ๐ง๐๐ฝ๐ฒ ๐ฎ civilization is one that is successfully harnessing ๐ข๐ญ๐ญ the energy resources ๐ณ๐ฟ๐ผ๐บ ๐๐ต๐ฒ๐ถ๐ฟ ๐๐๐ฎ๐ฟ ๐๐๐๐๐ฒ๐บ.

There could be more after Type 3, but this is the general idea.
Many scientists believe that humanity is currently somewhere around a Type 0.6 or 0.7. ๐ง๐ต๐ฒ ๐ผ๐ป๐น๐ ๐๐ฎ๐ ๐ณ๐ผ๐ฟ ๐ฎ๐ป๐ ๐๐ฝ๐ฒ๐ฐ๐ถ๐ฒ๐ ๐๐ผ ๐ฟ๐ฒ๐ฎ๐ฐ๐ต ๐ง๐๐ฝ๐ฒ ๐ญ ๐ฎ๐ป๐ฑ ๐ฐ๐ผ๐ป๐๐ถ๐ป๐๐ฒ ๐ผ๐ป ๐ถ๐ ๐ฏ๐ ๐ฎ๐ฑ๐ผ๐ฝ๐๐ถ๐ป๐ด ๐ฎ๐ฏ๐๐ผ๐น๐๐๐ฒ๐น๐ ๐๐ผ๐๐ป๐ฑ ๐ฒ๐ป๐ฒ๐ฟ๐ด๐ ๐บ๐ผ๐ป๐ฒ๐. This means that if there are other civilizations in the universe, they have not contacted Earth yet because they either have not adopted perfectly scarce digital money yet, or they have, and theyโre on their way.
And who knows? Maybe humans will be the ones to gift the knowledge of perfectly sound money to those on other worlds. Only time will tell.

What do you think of that answer?
Let me know in the ๐๐ผ๐บ๐บ๐ฒ๐ป๐๐๐
๐๐ถ๐ธ๐ฒ๐ค and ๐ฆ๐ต๐ฎ๐ฟ๐ฒ๐ this if this gave you hope for a better future.
And ๐๐ผ๐ผ๐ธ๐บ๐ฎ๐ฟ๐ธ๐ this for quick-reference, the next time you hear about the Great Filter, the Fermi Paradox, or the Kardashev Scale.
