If we are talking about a single neural network that can do everything in real-time, then the only viable path I am aware of is spiking neural networks.

When you are working with I/O, you need to be very sensitive to time domain considerations. Training a periodic timer (i.e. polling for a response) into the current crop of transformer models does not seem feasible outside of clunky agentic approaches that invoke some external tool.

Yes and that bit sounds to be relatively easy to automate.…

I was assuming that the "general purpose computing" training dataset would be so unfathomably large that unsupervised learning would be a necessity. Who is going to label the "general purpose computing" training dataset and how would it be persisted?

> Who is going to label the "general purpose computing" training dataset

That's what i imagined to be easy to automate. We have tons of inputs* and real computers, that will output what real computers would output.

* and hopefully the knowledge to come up with a set of inputs that (together with an actual general purpose computer) contains the essence of what general purpose computing is.

I think it’s very much a magical fantasy computer :-) A thought experiment, rather than a claim to something that’s been built or exists. The questions you pose are interesting ones, for the sake of the experiment I think at least: - Programming - Loading new software - Adding new functionality - Persisting user data Could all at least in principle be achieved without changing the network architecture, but rather jus…

True, but there are ethical and rights considerations unless you are building / growing an artifical brain.

You can't just grab a human or sufficiently-suitable animal brain and turn them into your personal mentat (https://en.wikipedia.org/w/index.php?title=Organizations_of_...) or computing servitor (https://warhammer40k.fandom.com/wiki/Servitor) to do your computing for you. (At least, not ethically.)

Where would you get a brain to train?

Also, it's not easy to train human / animal brains in their natural state as any parent / animal trainer can attest.

This reminds me of people in the past comparing computers as another brain because circuit network is similar to brain. I guess it is not impossible to construct one neural net. But how to train them, modify them (to add more programs), maintain them (security purpose), and make sure they are correct will be impossible in the near future (in my view). It would be crazy to see a madlad tunes every neuron to make a proof of concept though.

"100% Fully Software 2.0 computer. Just a single neural net and no classical software at all. Device inputs (audio video, touch etc) directly feed into a neural net, the outputs of it directly display as audio/video on speaker/screen, that’s it." Sounds like a magical fantasy computer. How would the input and output devices work without drivers? Does "no classical software at all" mean that the drivers are somehow wi…

It is not magical if it is allowed by the laws of physics

That's why I'm introducing my new Quantum Heisenberg computer. It works until you observe it.

That's my impression, yeah: the neural net would learn to associate input signals with output signals. If this could ever be made to work then it'd have some pretty neat implications for human prosthetics.

> How would such a magical neural net computer be trained?

You'd need some way to praise or scold the thing. Probably a debug line or something to encode pass v. fail.

> How would you program such a computer or load new software onto it? If the whole thing is a single neural net, wouldn't the neural net need to be replaced in order to add new functionality or correct errors/bugs?

I think you answered your own question: swap out the entire neural net (which would probably entail a hardware swap unless you're able to train a neural net to replace itself).

> How would user data be persisted while upgrading the applications?

Train the neural net to interface with a hard drive?
