Reply to comment by Shelfrock77 in Nanowire Synapses 30,000x Faster Than the Human Brain have been created for the first time. by AylaDoesntLikeYou

My brother thinks none of this will happen in our life time, I keep telling him we will have a GTX 4080 compressed into the size of a cell phone, when they have the materials which run faster and cooler than the current tec.

I give it less than 10 years.

The physical limits of computing is:

> At 20 °C (room temperature, or 293.15 K), the Landauer limit represents an energy of approximately 0.0175 eV, or 2.805 zJ. Theoretically, room-temperature computer memory operating at the Landauer limit could be changed at a rate of one billion bits per second (1 Gbit/s) with energy being converted to heat in the memory media at the rate of only 2.805 trillionths of a watt (that is, at a rate of only 2.805 pJ/s).

Which means trillions of times less power than a lightbulb for a gigabyte internet is the theoretical limit.

Maybe zettabit/s computing power on a lightbulb of energy.

Started reading the comment thinking that you were explaining why it's not going to be possible, finished reading the comment happy that we are no where near the theoretical limits and that there is a massive amount of ground still to cover.

Needs to be smaller than that and portable energy sources are the main bottle neck still in regards to reducing the size of computers. Best we got is carrying a battery the size of a suitcase that can charge using solar panels. Idk how we can make energy sources smaller than that. I hate being dependant on the electrical grid.

And if you want to travel they limit the battery size on planes that you can bring for safety reasons. So there's still a lot to figure out in terms of energy sources for portable devices of that caliber.

It is, could you imagine a mega drive or amiga computer in the size of your phone, because it can emulate any games on them.

I can't wait for the future.
