I’m legit wondering. is there a compujter that isn’t a Turing machine. quantum computers don’t count because they aren’t real.

ibm just released a new quantum computer op https://www.vox.com/future-perfect/2023/12/6/23990752/quantum-computers-ibm-google-honeywell-china-supercomputer-artificial-intelligence

yeah kinda. its not really very useful right now though. tbh i don't think any of them are, but they do exist ibm's site has a lot more info about it https://www.ibm.com/quantum/technology

technically all computational devices we'll ever build are merely finite state machines, not turing machines, since the latter is defined to have an infinite tape

what's the point of having an infinite tape? you're never gonna be able to use most of it. seems like some dick measuring contest thing

idk every quantum computer I have seen has a lot of impressive looking copper blocks and piping but doesn't look like an actual machine that can do work. I think its all woo

they do generate a lot of heat and move air.

if you want to talk externalitys, the computations of the computer cause a lot of people and or machines to do work

probably not. most of the work seems to be devoted to making a number go up for some of the worst people

I think its all woo i don't know a whole lot about how these things work but apparently they are having trouble stabilizing the cubits to the point where they're not making so many errors that they're basically useless. there was an interview with ibm's head quantum computing guy and i thought it was pretty telling when asked if their new quantum computer can do computations that a regular computer can't, replied with something to the effect of like, "oh, yeah, they can do calculations" like, not faster, more of them, ones impossible to solve currently, etc. — just that they can do unspecified calculations, sometimes

and by not quite I mean not even close. I did however implement half of a risc style cpu in logisim

video cards with programmable shaders are Turing complete, op. but they suck at it.

Beeftweeter posted:doesn't that mean the geforce 2 is technically turing complete the geforce 2 didn't have programmable shaders. the first few generations of graphics cards that did have programmable shaders weren't turing complete either since you had no way to control the flow of execution in the shader. so no general if statements or loops that can't be unrolled at compile time. the closest to an if statement was that some instructions supported conditional predicates, but there were no instructions that modified the instruction pointer like jumps basically to be turing complete you need the wonderful ability to get stuck in infinite loops, something modern gpus can do with aplomb as evidenced by the regularity with which windows kills my graphics drivers when i write buggy shaders
