Fireship does great explanations
the video explores different processing units used in computers. GPUs are essential for tasks like rendering graphics and training deep learning models. TPUs, on the other hand, are designed specifically for tensor operations required in deep learning and can save significant time and cost when training models. DPUs, or data processing units, are optimized for moving and processing large amounts of data in Big Data Centers, relieving the CPU from such tasks. Finally, there is the potential for the development of QPUs, or quantum processing units, which operate using qubits instead of classical bits and have the potential to revolutionize computing with their ability to handle complex algorithms exponentially faster. However, the threat they pose to encryption and security is also a concern.
Correct. I see QPUs as any major advancement that comes about. Our knowledge of how to make iron things for instance. On one hand, we were able to reinforce our buildings, boats, and wheels. Which were all great improvements for humanity. On the other hand though… our knowledge of iron brought about stronger weapons. Swords, spears, and even better catapults. All things that often bring on wars and destruction. As soon as an advancement becomes established, it can bring about both great and horrible situations for the world. It always depends on who wields the knowledge and their desires.
That being said, I strongly feel that quantum computing can bring an unthinkable leap forward for humanity. Where we unlock great/major advancements at half the time or greater. But like the example above, this could also set us back if used for warfare, destruction, cyber attacks, and collapsing whole corporations,/industries/governments. The next 20-30 years I believe will either bring the end of the human race or the start of a whole new stage of human existence.
silicon is really inefficient: too much power wasted in form of heat (Joule effect), on the other hand, quantum computing functions in absolute zero conditions, so no inefficiencies. in a perfect world, one would outsource all its calculations to a quantum instance, but the thing is too costly and centralized; if everyone could afford low latency internet our phones wouldn’t require cpus and gpus, instead we could run them on a quantum computer, but since its too centralized, the issue of privacy would prevail. Would be nice if we had quantum instances scattered around, like lemmy instances, but donations won’t probably cut it to cover costs, so we r stuck with sand computers for now
