Reminds me of this: https://ieeexplore.ieee.org/document/4051190 https://ieeexplore.ieee.org/document/4051190 Back then a digital computer couldn’t hold a candle to an analog one and processed only a few bits at a time. It was slow and imprecise. Look at where we are now. A general quantum computer is a fundamentally different kind of computer. Those who cannot imagine what can be done with one lack the imagination to understand foundationally new technology and are unable to invent their own.

It seems that nobody on the planet is able to invent their own quantum computer.

  Actually, a 65-qubit quantum computer has been created. "IBM's current largest quantum computer, revealed this month, contains 65 qubits." https://www.science.org/content/article/ibm-promises-1000-qubit-quantum-computer-milestone-2023 https://www.science.org/content/article/ibm-promises-1000-qu...

    I'm not an expert but I think because of the error correction mechanisms the effective number of quibits is smaller than that

      No quantum computing platform today has meaningful error correction. What you can get, in some cases, is limited error detection based on the outcome of the question computation, if it's built into your specific algorithm.

    There is a big difference between a practical QC and the QC we have now. 65bits isn't practical for any known real problem but ask also how long it takes to boot it, how many cycles it can execute per run and how many runs it can do per day (or week). These thing are not like your laptop, they are more like particle accelerators.

We went from analog to digital computers because of the concrete and specific attributes of digital computers that made them useful. Saying we went from A to B, therefore we will go from B to C, regardless of what C is makes no sense. "Things change, therefore this new thing is good and you simply lack the imagnation to understand why" is about as bad of an argument as it gets. It's also funnily enough mirrors the everlasting blockchain advocacy.
