I really do not grasp business when PayPal is somehow worth over $50 Billion

It doesn't have assets? It's not a bank

Is it because PayPal is integrated already into so many websites?

Wouldn't it take decades to make back $50 Billion in fees?

ck2 — Wed, 15 Jul 2026 12:34:47 +0000

because of how we evolved biologically, there are some processes, particularly in the brain and not just the body, that can only happen during sleep

like "garbage collection"

first we have to stop current administration from funding NEW coal power plants and defunding wind turbines

but I am not sure we can ever undo this much damage

remember when they filled that lake or city water supply with black floating balls to greatly reduce evaporation

don't supposed that is possible on much larger bodies of water

Needless to mention it was 100% theater and absolute destruction of government was simply the point

US Treasury is borrowing $155 billion every month is now paying $24 billion a week in interest

And at least $21 TRILLION of the $40 TRILLION national debt is from militarization

ck2 — Mon, 13 Jul 2026 12:43:19 +0000

if you really, really want to understand physics and are not afraid of hard math I highly recommend this youtube channel in particular

* https://www.youtube.com/@PhysicsExplainedVideos/videos

"Physics Explained"

But I am not kidding about hard math

He starts off slow and gentle but most of the videos 10 minutes in my brain is screaming and cannot keep up

Which is probably why textbooks are superior for some kinds of learning

But his videos are very well done

Landing on something 1 BILLION kilometers away, only 41 meters wide, wildly spinning. would definitely be a flex

New comment by ck2 in "Leaded gas was a known poison the day it was invented (2016)"

ck2 — Sat, 11 Jul 2026 18:52:17 +0000

the amount of lead that is acceptable is ZERO

ZERO, thirty years ago when there was definitive proof is it forever and irreversible

all lead exhaust aircraft should have been phased out a decade ago if not two decades ago if they cannot be converted

again, there is no acceptable amount, imagine it being sprayed on you, your car, everywhere

your body tries to process it like calcium and stores it forever

how much damage and disease to you and your family are you willing to accept just so someone can keep using their prop aircraft for another decade to make profit?

yes it's all about the money, it's pretty obvious, if there wasn't profit involved it would have been phased out with cars THIRTY YEARS ago

all that lead sprayed all around the land and on people is FOREVER, it doesn't go away, it doesn't wash away, it doesn't evaporate

ck2 — Sat, 11 Jul 2026 17:52:02 +0000

and still sprayed all around the surrounding land at almost every airport in the USA and worldwide from prop aircraft exhaust despite knowing ANY amount is toxic and irreversible for 30+ years

at some point some rogue country is going to do a starfish-prime event

create an artificial LEO radiation belt on purpose and wipe out 99% of satellites

part of me is oddly rooting for it these days

we cannot have private trillionaires milking "privatize the profits and social the costs"

no more, it has to end immediately

they aren't just silo-ing their wealth, they are leveraging against societies, funding far-right violent politics against society

even the evil Koch-brothers have cancer wings in hospitals around the country, Musk doesn't give a dime to charity, just his own foundation which he controls to only do what he wants to manipulate

pre-pay costs to society before damaging society

no, just no

make them pre-pay a multi-trillion cleanup and cancer fund for all the toxic waste, not just the launches but pollution burning up in the atmosphere

New comment by ck2 in "QuadRF can spot drones and see WiFi through my wall"

ck2 — Fri, 10 Jul 2026 17:55:26 +0000

I'm reading about pilots spotting drones during takeoff/landing that the airport didn't know about

And I've read about airport shutdowns in UK and US without a single arrest which is why it keeps happening

So whatever system exists, apparently not good enough

New comment by ck2 in "QuadRF can spot drones and see WiFi through my wall"

ck2 — Fri, 10 Jul 2026 16:14:50 +0000

if it can spot/track drones that is a marketing opportunity for airports around the world that have to deal with drone nonsense which shut down flights for days

if you aren't afraid of difficult math breaking your brain, I highly recommend this youtube channel "PhysicsExplained" (sorry I forget his actual name but he is brilliant)

he has a recent two-parter on Maxwell and electro-magnetism that are EXCELLENT
