Technology

The past is where we get all of our information from. To pretend like we can't use the past to predict the future makes us unable to do anything. We don't have a time machine to go see exactly how the future plays out.

It is more common than you realise for their to be predictable trends in computing. Just go look at Moore's law and how long it has held up(with just minor adjustments). What would be way more surprising is if we are all of a sudden at a massive turning point where we can no longer anticipate what is next. You don't have to take my word for this. Find anyone with a background in computing to independently verify it. Even chatgpt could really help you understand this.

The specialized hardware efficiency gain isn't even a mystery at all. It is simply the consequence of designing hardware that does a specific task very well. It isn't nearly as much of a guess as you think it is. To help you picture it, imagine a vehicle that works on land, sea, and sky. It is not such a leap to say that a vehicle made to work for just the land would be much more efficient at being on land. This really isn't anything that anyone in the computing world disagrees with. It is just your outsider point of view that is making it seem like magic to you. Again, don't take my word. This is comp science 101 stuff that really isn't disputed.

So far as the thought experiment with replacing neurons. The technology to do so doesn't need to exist for the point to hold true. That simply isn't a logical requirement for thought experiments. This has nothing to do with computing or anything. This is just true of logical arguments. In order to make points, we can use thought experiments. This is something that Einstein was famous for, and not many people question his ability to form solid arguments.

I understand that you feel passionate about this, and you really want this idea that humans are somehow magical and fundamentally different from machines. It really is understandable. I've given plenty of solid arguments that you really haven't responded to at all. It has never been true that people can't use thought experiments or past trends to help make conclusions about the future. It is very telling that these are things that you feel like you must discard in order to defend your stance. These are both things that have been reliably used for hundreds and even thousands of years.

I would really encourage you to get ahold of some logical reasoning material and try to take a step back to some basics if this is something that you are interested in digging a bit deeper into this. It is almost never the case that initial hunches turn out to be kept after thurough investigation.
