Imagine a scale that ranks civilizations not by their borders or technology, but by the sheer energy they command— some spanning entire galaxies. Join us as we explore the Kardashev Scale, the ultimate measure of cosmic power.

The Kardashev Scale & Population

The Kardashev Scale & Population (Narration Only)

This concept was introduced to me by Elon Musk on Twitter. 

https://en.wikipedia.org/wiki/Great_Filter
https://en.wikipedia.org/wiki/Fermi_paradox

[Verse 1]
I was sittin’ one night, starin’ up at the sky,
Wonderin’ why no aliens swing by.
Are they hiding away or just too shy?
Or did they all never reach for the sky?

[Pre-Chorus]
Then Elon Musk said, "Let me clue you in...
"There’s a reason no Martians come crashin’ in!"
I said, "What’s the deal? Where did they go?"
He smiled and said, "Well, here’s what we know..."

[Chorus]
Oh, it’s the Great Filter, keepin’ folks away,
Maybe they exploded and got blown away!
Did they make it to land and come out of the sea?
Or never get past the one-cell amoebae?

[Verse 2]
Maybe life out there is stuck in the gloom,
Never quite made it to me or to you.
Or maybe they built robots, got lazy and fat,
Then the bots took over, and then that was that!

[Pre-Chorus]
So are we the first, or are we next?
Are we cosmic winners, or a failed test?
Will we spread to the stars or meet our doom?
Or just sit here watching cat vids on Zoom?

[Chorus]
Oh, it’s the Great Filter, keepin’ folks away,
Maybe they exploded and got blown away!
Did they make it to land and come out of the sea?
Or never get past the one-cell amoebae?

[Bridge]
Maybe space is just too wide,
Too hard to cross, too tough to ride.
Or maybe the aliens are out there near…
Took one look at Earth and said "Nope, not here!"

[Outro]
So I’ll sit right down with my radio set,
Hoping to catch some cosmic text.
And if they’re out there, hope they say "hi"
And not, "you folks are boring, we're passing you by".

AI Collective - Fermi's Great Filter

A dramatic cinematic, film score soundtrack.

March of Seti

Consider, if you will, a sequence of symbols—6EQUJ5—etched into the annals of astronomy, a cryptic whisper from the depths of space. Once, it was a burst of radio waves, the Wow! signal, a fleeting enigma that haunted our telescopes. Now, in February 2025, it has become a melody. A human act of alchemy, transmuting mathematics into music, static into song.

The Wow signal melody

WOW! Signal Medley.MP3

It can be hard to hear a signal 100 miles away—so what does it take to build a beacon loud enough to be heard 100,000 light years away? In this episode, we explore galactic beacons: powerful transmissions that may teach, warn, or outlast the minds that made them.

Hi all, so from 2016 to 2024 I assembled and produced a large collection of covers of many of my favorite tunes as my own hobby (and many during COVID lock-downs!) and I have accumulated over 2,800,000 plays across the world which is awesome!

I am much more of a producer that a musician. These first 8 years of my music was mostly based on midi cover tracks often downloaded from the Internet but heavily reproduced and re-imagined variously on my two Yamaha keyboards (Clavinova and PSR 975), but also using PC midi editing & DAW software.

Towards the end of that period, I added some of my more original electronic music which I produced over the past two decades under the name of Funkleberry in order to consolidate my Soundcloud accounts. 

But in 2024 I got into AI music generation and I am now  a freelance sonwriter and AI music producer. It's been a fun journey!

My first 4 AI Albums can also be found here:

in Apple music (search Funkinova and/or AI Collective)

If you like anything you hear, please pass them on!
