Apple's Silicon Magic Is Over!

Chips are reaching the physical limits of what is possible. According to a video I watched today, an experimental 1 nm process only has 1 atom per transistor. That doesn't sound right to me, but if true, then you can't go smaller than that.

There might still be some room for improvement, but smaller circuits tend to fail because quantum effects cause electrons to jump between circuits.

Someday computers might have circuits that use light instead of electricity, but right now the technology is not even close.

What would it mean if computers can't get much faster? If you need more computing power then you would need more chips, or bigger ones, that either way consume more energy.

However, it feels like computers are plenty powerful right now. It is not like the general public has a strong need for more powerful chips.

Apple already has good competition from AMD. My mini computer is twice as powerful as the Apple M2 chip.

A Look Inside Apple's $130 USB-C Cable

Apple sells things at a higher margin than other companies.  Although this is a superior cable for data transmission, maybe competitors will offer comparable products.
