1 00:00:00,240 --> 00:00:07,800 this is Gordon Moore he co-founded Intel but\h before that he came up with the law not a classic\h\h 2 00:00:07,800 --> 00:00:13,200 like don't murder or no white shoes after Labor\h Day but one that nevertheless changed the world\h\h 3 00:00:13,200 --> 00:00:20,820 in 1965 he noticed that transistors a component\h of microchips had shrunk really fast since 1959.\h\h 4 00:00:20,820 --> 00:00:26,340 his law predicted that every 18 months the number\h of transistors Engineers could fit on a microchip\h\h 5 00:00:26,340 --> 00:00:33,360 would double in 1975 He adjusted the doubling time\h to every two years still exponential growth just\h\h 6 00:00:33,360 --> 00:00:39,000 a little Chiller depending who you ask Moore's\h Law either proved true or was a self-fulfilling\h\h 7 00:00:39,000 --> 00:00:44,520 prophecy the young semiconductor industry cranked\h out smaller and smaller transistors at roughly\h\h 8 00:00:44,520 --> 00:00:51,540 the rate more predicted and computers got crazy\h good Crazy Fast the first planner transistor from\h\h 9 00:00:51,540 --> 00:00:59,640 1959 had a transistor count of one the chip in the\h iPhone 14 pro has a transistor count of 16 billion\h\h 10 00:01:00,180 --> 00:01:08,040 16 billion that's a lot to fit on one chip I had\h one of my writers Amy see how many grains of rice\h\h 11 00:01:08,040 --> 00:01:12,600 she can fit on one ship and she only got to 261\h before she called the National Labor Relations\h\h 12 00:01:12,600 --> 00:01:19,260 Board and with that skyrocketing transistor\h count came smaller more powerful devices the\h\h 13 00:01:19,260 --> 00:01:23,580 Apollo guidance computer the one that allegedly\h got those actors to the Moon had the computational\h\h 14 00:01:23,580 --> 00:01:32,100 power of about 15 000 flops but it was only about\h 0.25 of the nes's power the Xbox had more than\h\h 15 00:01:32,100 --> 00:01:38,820 six times the power of the iPhone 4 the Xbox 360\h had more than 10 times the power of the Xbox by\h\h 16 00:01:38,820 --> 00:01:44,700 comparison advancement in just about every other\h industry looks like turtle racing I mean in that\h\h 17 00:01:44,700 --> 00:01:51,180 same time McDonald's fries got worse bring back\h the animal fat when he came up with his law Moore\h\h 18 00:01:51,180 --> 00:01:55,620 saw his industry as an exception to the far more\h iconic Murphy's Law which says that anything that\h\h 19 00:01:55,620 --> 00:02:02,460 can go wrong well because in chipville things only\h go well and then better but now despite all those\h\h 20 00:02:02,460 --> 00:02:09,360 glorious years of exponential growth Moore's\h Law is dying mosfit transistors now the single\h\h 21 00:02:09,360 --> 00:02:15,900 most manufactured human-made object in history\h literally cannot get any smaller because physics\h\h 22 00:02:16,680 --> 00:02:23,280 to understand why because physics I gave Amy a\h sociology major a couple days to get up to speed\h\h 23 00:02:23,280 --> 00:02:28,260 on The Cutting Edge of semiconductor engineering\h and quantum mechanics then I stole her phones\h\h 24 00:02:28,260 --> 00:02:32,760 so she wouldn't call the nlrb again here's\h what she wrote you probably know that your\h\h 25 00:02:32,760 --> 00:02:38,280 computer works in binary code zeros and ones\h transistors basically are those zeros and ones\h\h 26 00:02:38,280 --> 00:02:44,280 if a transistor is letting an electrical current\h through one if it's not zero the more transistors\h\h 27 00:02:44,280 --> 00:02:49,260 on a chip the more complex the information your\h computer can process and the quicker it can do it\h\h 28 00:02:50,280 --> 00:02:53,880 this transistor is made up of a bunch of\h silicon atoms peacefully holding hands in\h\h 29 00:02:53,880 --> 00:02:59,460 four directions via their valence electrons\h spice the silicon crystal over here has some\h\h 30 00:02:59,460 --> 00:03:04,140 phosphorus in it which has a fifth valence\h electron running around loosey-goosey over\h\h 31 00:03:04,140 --> 00:03:08,100 here there is no phosphorus but there is\h some Boron which with only three valence\h\h 32 00:03:08,100 --> 00:03:11,700 electrons has created holes that the other\h electrons are running around trying to fill\h\h 33 00:03:12,480 --> 00:03:17,940 where these two areas meet we've got the depletion\h layer the bonus electrons from this side fill\h\h 34 00:03:17,940 --> 00:03:22,320 the holes from this one creating a negatively\h charged area that repels any spare electrons\h\h 35 00:03:22,320 --> 00:03:27,540 floating around phosphorus town that prevents the\h current passing through so the computer reads zero\h\h 36 00:03:28,140 --> 00:03:33,360 if you apply just a little positive voltage here\h you neutralize the depletion layer and electrons\h\h 37 00:03:33,360 --> 00:03:41,760 flow freely AKA one that's how transistors work\h but why can't they shrink anymore today there are\h\h 38 00:03:41,760 --> 00:03:47,700 transistors that are just two nanometers wide the\h width of 10 silicon atoms if you go much smaller\h\h 39 00:03:47,700 --> 00:03:51,960 electrons will be able to just hop the depletion\h layer and flip zeros to ones at random thanks to\h\h 40 00:03:51,960 --> 00:03:58,020 a little move called Quantum tunneling see at\h this tiniest scale there's innate uncertainty\h\h 41 00:03:58,020 --> 00:04:02,820 as to where things are and how they're moving\h you can't just look at a particle and say it's\h\h 42 00:04:02,820 --> 00:04:07,740 there you have a wave and its matching probability\h function tells you it's most likely there or there\h\h 43 00:04:07,740 --> 00:04:13,020 but it could also be there but probably not there\h it's not that intuitive but if you've ever used a\h\h 44 00:04:13,020 --> 00:04:18,360 public transit system or a highway you've dabbled\h in the quantum physics mindset Google Maps tells\h\h 45 00:04:18,360 --> 00:04:22,740 you your trip will take 25 minutes with classical\h physics level certainty but you know that between\h\h 46 00:04:22,740 --> 00:04:27,180 traffic missed trains and your personal Need\h for Speed you're probably looking anywhere from\h\h 47 00:04:27,180 --> 00:04:34,200 17 to 31. that's how things go at the quantum\h level it's all probability so let's look at an\h\h 48 00:04:34,200 --> 00:04:38,880 electron approaching the depletion layer with that\h mindset when it hits the barrier it creates this\h\h 49 00:04:38,880 --> 00:04:44,280 exponential decay curve and dies out inside its\h electron is going to be here with no weirdness but\h\h 50 00:04:44,280 --> 00:04:48,600 if we shrink the barrier small enough that wave\h doesn't die in the barrier and some probability\h\h 51 00:04:48,600 --> 00:04:52,560 survives to the other side meaning we have to\h accept that even though classical physics say\h\h 52 00:04:52,560 --> 00:04:57,300 he'll be over here quantum physics says there's a\h non-zero chance that Mr electron will pop up over\h\h 53 00:04:57,300 --> 00:05:02,940 here and let the current through that's Quantum\h tunneling and if it's not take it up with Amy\h\h 54 00:05:02,940 --> 00:05:08,880 though I'm silverphone so she probably won't see\h your text if a transistor gets too small electrons\h\h 55 00:05:08,880 --> 00:05:12,840 can just Quantum tunnel through the depletion\h layer and flip a zero to one at random screwing\h\h 56 00:05:12,840 --> 00:05:17,280 with all that very important math your computer\h is doing you're opening the door for Murphy's\h\h 57 00:05:17,280 --> 00:05:23,100 Law anything that can go wrong will if you put a\h bajillion Quantum tunneling from transistors on\h\h 58 00:05:23,100 --> 00:05:28,260 a chip you'll get a lot of quantum tunneling\h transistors this Wii wouldn't make computers\h\h 59 00:05:28,260 --> 00:05:34,620 better they'd mess them up and so subatomic\h Murphy's Law kills more spawn it had a good\h\h 60 00:05:35,760 --> 00:05:43,680 so what now do computers stop getting better sadly\h no humans are Innovation gluttons who'll just keep\h\h 61 00:05:43,680 --> 00:05:49,080 making computers better until we finally die by\h their hands the end of Moore's Law just means that\h\h 62 00:05:49,080 --> 00:05:53,460 computers can't keep getting better in the exact\h same way that they have since they hit the scene\h\h 63 00:05:53,460 --> 00:05:59,400 instead the dweebs have to figure out something\h new like Quantum computing I asked Amy to whip up\h\h 64 00:05:59,400 --> 00:06:05,340 a quick explanation of that so let's see what we\h got eat Rock's bonehead well that's not very nice\h\h 65 00:06:06,360 --> 00:06:12,660 what's also not very nice is grocery store\h coffee it's just so mid it's not terrible\h\h 66 00:06:12,660 --> 00:06:17,280 but the beans are just boring and mediocre and\h monotonous and it kind of just takes all the joy\h\h 67 00:06:17,280 --> 00:06:21,540 out of making coffee at home so what happens\h to me and I'm guessing you is that I give up\h\h 68 00:06:21,540 --> 00:06:25,440 making coffee at home and revert to spending six\h or seven dollars on a latte and you know what the\h\h 69 00:06:25,440 --> 00:06:31,380 financial experts say if by latte no can have home\h so you're faced with only bad options you either\h\h 70 00:06:31,380 --> 00:06:37,320 kill your finances by going to a coffee shop or\h drink boring grocery store coffee unless you use\h\h 71 00:06:37,320 --> 00:06:43,620 Trade coffee you see they're a coffee subscription\h service
