Bullshit like this always angers me. "Yeah ancient civilizations were so advanced, or aliens did this". They put cut rocks on cut rocks, and when you have thousands working on a pyramid, then it's not that hard to complete. Not to discredit ancient Egyptians, this is still impressive, but the concept is simple. Now we send shit to mars, build kilometer high skyscrappers, flying metal vehiclesin the sky
Exactly, although kilometre high skyscrapers are still "easy" by comparison.
We invented this thing called a transistor, then we put billions of them onto something the size of your little fingernail...then we shit out millions of these flawlessly, for a reasonable cost.
That is where our impressive construction has gone.
To be fair, it's only wireless to your closest base station then it uses wires to the other side of the globe.
And this is a cool tidbit: the reason it lags a bit when talking to someone on the other side of the globe is the speed of light. We transfer stuff with bits (very basically a light blinks on your end of the globe and another reads the blinks on the other end, I'm skipping over a ton here but in a nutshell that's how it works) and since the other side of the globe is 20k kilometers away it takes light about 120ms to reach your buddy and back.
Which is also why you have high ping when playing games on servers that are overseas.
Bro and what's with us storing data in actual clouds. Like, those little shits up there blocking the sun can rain on us AND store our data? It blows my mind.
Even more fucking crazy and even more fucking amazing is how gps and lidar arrays works. They literally fucking calculate the time interval of travelling light between satellite and phone (in gps) and then general relativity so it won't drift over time.
And then we shove them into a smartphone that sits in our hand. Which already had billions or transistors that make electrons dance in specific way so send our shitty memes to our crazy friends.
I haven't even talked about dna modification for treatment of some dieses WTF 😭.
This sphere is literally powered by thousands of these chips working in harmony, it's the next evolution really. Humans have always built on top of other human accomplishments. That's why we are special.
Perfect is maybe an overstatement. At least when I heard it, the reason we have i3's 5's, 7's and 9's isn't because because of the consumer. Only the top of the line is perfect, the i9, the rest of the chips have some faults in them that cause them to not work. And since perfect chips are somewhat rare, but it's fairly easy to just turn off some of the (non-functional) cores on a chip, we get the lower end CPU's to reduce waste and increase profits.
Yeah that's correct. Silicon fabrication has a yield, and a way of maximising yield is doing what you say, a technique called binning.
However all I meant is that we can churn out millions of them perfectly, not that each and every one of them is perfect. There are many high yield devices which also must be perfect (CCDs, FPGAs. etc.)
Also our manufacturing capabilities in general. The most advanced metalworking objects in antiquity are fairly basic geared mechanisms made by a highly skilled craftsman over the course of a year, done by hand filing and basic turning of small chunks of metal. A skilled machinist in modern times working 5 days a week on a project could build a vehicle capable of flying.
The most efficient of them, by the way, are produced at a reasonable cost in one factory, currently. Only one place on earth has been constructed that can do it with such a high level of precision. Takes insane amounts of technical knowledge, time, cash, and maintenance.
