[Ace_Unicrn]

Ah yes, Sciencephile giving me my existential crisis, just as prescribed by the AI lords intended

[rip_kaiza]

Scienephile has yet to break character. What dedication, respect

[thalt]

I love how AI has now gotten so advanced that Sciencephile could actually be a real AI and no one would notice

[jamestalbert]

The fact that killing other humans has become so accepted that it's made into a game and advertised in a video about existential threats is just gold.

- Sciencephile, 2023

[biglegs]

Love how half the S-tier threats to human existence aren't actually deadly, or anything I would ever need to worry about. Those chickens tho...

[fluffly]

Extra-dimensional evil chickens makes complete sense as a stand-in for outside context problems; that is, things that no one would even imagine is a possibility until it happens. If you can even define a tier for that it would probably be top S

[rubik]

Nothing better than a dose of existential crisis before going to sleep

[iVideoRandomStuff]

Imagine AI finally taking over Earth then a solar flare happens

[tyronewilliams]

So basically, the existential crisis was the friends you made along the way.

[Johnny-etpk]

For a true existential crisis simply ponder the fact that there are more airplanes in the sea than submarines in the sky

[trevorturner]

Jesus. your editing gets better every video.
Great work.

[hamdullaharya]

The biggest existential threat is the kid from 4th dimension erasing it’s drawing

[xarxos]

An interesting thought: The probability that the end of the universe ends up being what finally kills off humanity, is exactly equal to the probability that something else *doesn't* kill off humanity before then. Since the end of the universe is virtually guaranteed to occur eventually and there's no way humans can survive it, the only way to avoid going extinct from it is to go extinct from something else instead.

[NexusOne]

The greatest existential threat for the western world is having subscription to all streaming services but nothing good to watch.

[Mic_Glow]

if "no wars were ever fought" we would be 1000 years behind in tech. Some recent examples:
- space program, descendant of WW2 rockets
- reactors, from cold war arms race
- computers, vastly improved to crack military codes
- the internet itself was developed as decentralized means of communication in case of ww3

[Pascal_Link]

I read Vacuum Decay as Vacuum Day and was wondering why the day you vacuum clean your house, would be an existential threat lol

[yiioooooo]

Unfortunately I don’t think humanity has take the proper measures to combat an invasion from the overwhelming force of extra dimensional evil chickens, making that the most likely possibility of human extinction.

[KingMatthewXV]

An edgelord and a scientist are not the same. An edgelord wants the world end, a scientist knows it will.
