Moore's Law is dead. Basically the technology to make transistors was continuously getting better at a pretty steady rate, resulting in smaller and smaller transistors that let you shove more processing power onto the same sized chips for decades. Eventually, though, you hit that 5-7nm scale (yes, that means the transistors are literally a few molecules across. It's nuts.) and you start hitting quantum fuckery because now you're reaching a scale where electrons' probability clouds are large enough compared to the transistors themselves that you get a reasonable amount of them quantum tunneling through the transistor entirely, which makes your transistors not work very well.

Moore's Law being dead is actually a good thing though. Intel and AMD (and by that I mean Intel) have had a monopoly on CPUs for decades because the foundries to produce chips that complex are ludicrously expensive, easily billions of dollars a piece, and they stay that expensive because you're basically throwing them out every 2-4 years in favor of a newer, better foundry to make an even more complex chip. Once you hit that 5-7nm plateau though the technology becomes more established and the treadmill effect of ever-better-foundries stops, which allows other manufacturers to get into the game. You see this especially in the 14-28nm range of chips being made for ARM and RISC chipsets, the latter of which is open source. This means the price of quality hardware goes down because you no longer have to pay a premium to use a monopoly's chips, and you can avoid shit like Intel's NSA backdoors because now a smaller group can afford to break into the industry and make open source hardware. It also lets you pump out cheap less-powerful hardware for things like IoT sensors, clustered computing, etc so you can build Cybersyn 2: FALGSC Edition :cyber-lenin:
