Humans have been around for thousands of years. Look at what we've accomplished in the last hundred. We have artificial heart pumps now. In the next two hundred years, if cancer research doesn't slow down too much and if we find some quick fixes for neurodegeneration, I think it's entirely plausible that 90 will become the new 60. I doubt I'll be around for it, and we might never hit the "life extension outpaces people reaching their life expectancy" medical immortality Holy Grail; but in the abstract, there is hope.
On the other hand...all of the medical advances up till now mean some of us (who live in the right place and have enough money) will live better, but up to now, we don't really live longer. People have lived into their 90s for centuries, but a microscopically tiny number even now live into, say, their late 100s. The oldest was 122. And there's nothing concrete on the horizon that says "if we solve this problem, we'll live to 125", much less 200 or 500. If we cured cancer and heart disease tomorrow, that wouldn't change.
Sometime in the next 5 minutes, in evolutionary timescale terms.
We built the first calculating machines yesterday, and a few hours later they took us to the moon. Now we’ve got vastly more powerful ones in our pockets and they have the sum total of all human knowledge and infinite patience for our questions.
Give it a few more minutes. We’ll know soon enough if the sand we’re imbuing with life is our salvation or our doom or something else entirely.
They don't have the sum total of all human knowledge: a lot isn't digitised. Even a large portion of academic knowledge is tied up in oral tradition: how much more is this the case for other fields of endeavour? One cannot learn the local social conventions about waiting tables from reading Not Always Right.
Even in domains where (virtually) all the knowledge is available, and most tasks are exact variations of what has come before, like programming, the most powerful AI systems are mediocre, bordering on competent. Outside this idealised case, they may have "infinite patience for our questions" (up to the token limit, anyway), but they largely lack the capacity to provide answers.
Medical research is about the best example you could pick for something that current-gen AI systems cannot do. Most of the information about the human body is located in human bodies, and wholly inaccessible to every AI system. An extremely important part of medical research is identifying when the established consensus is wrong: how is AI to do that?
There is no reason to believe that LLMs will ever meaningfully contribute to medicine, in much the same sense there is no reason to believe that lawn ornaments will. Pen-and-paper calculations, and the engineering / manufacturing / etc work of humans, took us to the moon: the computers acted as batch processors and task schedulers, nothing more. Medical research done by humans is responsible for the past century of medical improvements. As much as I like computers, they won't be people for the foreseeable future.
Death is horrifying, but an unfounded belief that AI will save you is not a healthy coping mechanism. If you're looking for religion, there are far better ones. And if you don't think you're looking for religion, perhaps the "death gives life meaning" philosophies might suffice? All Men are Mortal by Simone de Beauvoir was presumably some comfort to its author, who also wrote:
> There is no such thing as a natural death: nothing that happens to a man is ever natural, since his presence calls the world into question. All men must die: but for every man his death is an accident and, even if he knows it and consents to it, an unjustifiable violation.
I built one from discrete transistors in a lab class in college, on a breadboard. Fun times debugging and getting it to work. Then I flashed an led with it right next to another led flashed from a 555 chip. With the same discrete timer caps, the flashing frequencies were different due to the extra parasitics in the breadboard discrete 555 version. So had to compensate the caps to make the flashes match each other's frequency.
That's a great exercise. The hard part is always that in chips you can pull stuff that is rather tricky discretely, for instance, a multi-emitter transistor. So you can't always do a 1:1 conversion but for a 555 it is still doable.
Only because odd components aren't marketable. There used to be 4-terminal MOSFETs, they weren't sold after ICs became normal. Never heard of a multi emitter transistor being sold discretely but it's possible.
Dual gate mosfets were a godsend when building RF/IF mixers or preamps. Luckily I have a small stash as they're almost unobtanium and costly these days, but for most uses such as mixers and preamps they can be swapped with a pair or normal jfets in a cascode configuration like this one: https://i.stack.imgur.com/6Nyhg.gif
Omg... and thinking that my mother throws a huge stash of components like that. my father was an electrical engineer and ham radio. At least, I managed to save a stash of electronic valves and some analog equipment like an old oscilloscope that could be in a museum (I saw a similar model in a museum).
One of the books I first tried to learn from was _Miniature Projects for Electronic Hobbyists_ by one Ken W. Sessions. It was really a unijunction transistor project book. You know how some people will say you'll learn maybe not the best mental models for electronics from Forrest Mims' books? (I don't get it, they seem OK to me) Well, Forrest has nothing on Ken W. Sessions. The circuits worked, though.
Ok I chuckled
