semiconducter logic gates to q-bit logic gates is just “using physics to direct electrons again”.

I mean, even if they start getting quantum programming off the ground, no one is going to be able to afford the fucking computers. We can't even afford non quantum computers anymore.

Boiling water is just the layer 1 physical transport, all the cool stuff is happening at layers 2-7. The real mind blowing breakthrough would be if they finally did something to fix layer 8

I don't understand this layer stuff

Computer networking has the OSI model which I think is the analogy: https://simple.wikipedia.org/wiki/OSI_model

I had no idea there was a simple Wikipedia! I love these guys and am glad I'd donated when asked those times...

but those layers go to 7... layer 8?

[–] Narauko@lemmy.world 2 points 1 hour ago

Layer 8 is colloquially the User, as that is the next "layer" up above the application. Only really used in a troubleshooting context indicating where the issue took place, it's the networking equivalent for an PEBKAC (problem exists between keyboard and chair). For this analogy, layer 8 would probably be physics itself though.

I felt the OSI model was pretty relevant because while speeds and latency has improved astronomically, it is all still run off of the Ethernet framework and the humble copper twisted pair and fiber optic cable aren't really substantively different than they were in the 70s.
