Research.

Researchers have developed a new kind of nanoelectronic device that could dramatically cut the energy consumed by artificial intelligence hardware by mimicking the human brain.

The researchers, led by the University of Cambridge, developed a form of hafnium oxide that acts as a highly stable, low‑energy ‘memristor’ — a component designed to mimic the efficient way neurons are connected in the brain.

Yeah. I can believe that forces within the human brain could help AI reduce it's power consumption.

Step 1) Turn off AI.

Step 2) There is no step 2.

At least, that's what my brain thought.

could dramatically cut the energy consumed by artificial intelligence hardware

Decreasing the cost of using a resource almost always results in more use of that resource.

Laboratory tests showed the devices could reliably endure tens of thousands of switching cycles

That's not very many when GPUs perform trillions of operations per second.

It'd probably be far more appropriate for an analogue system where it isn't being switched but it's rather what the model is burned onto

This seems like such a glaringly-obvious solution to lower inference cost that surely there must be some fundamental flaw in it... otherwise all of the big AI firms would be doing it, right?

Right...?

I was half-expecting that new material to be hubris.

I feel like memristors have been a buzzword for like 20 years now… am I wrong? Is it for real this time?

AI boosters are no longer allowed to explain what’s good about AI using the future tense. You can no longer say “it will,” “could,” “might,” “likely,” “possible,” “estimated,” “promise,” or any other term that reviews today’s capabilities in the language of the future.

Cool tech but very much in infancy. Good for them on getting a hype article but this in no way affects anything about computing tofay.

Shooting a large rocket full of tech bros directly in to the sun will have a similar effect.

[–] adespoton@lemmy.ca 2 points 11 hours ago (1 children)

Shooting a rocket directly into the sun would waste as much energy as current AI data centers, because it would have to shed all the earth’s momentum.

Better to just use a volcano.

We can sell tickets for people to take turns pushing. A dollar per participant sounds reasonable to me.

Oh great, now we’re gonna start polluting the sun? Can’t we contain our garbage to a single planet?

[–] bleistift2@sopuli.xyz 2 points 13 hours ago

All of the things you’d be polluting the sun with are already there.
