It takes many years to train it though

Takes me back... There was significant hype around those things when they first managed to build them at scale (~15 years ago), because they were promising for low power, high density persistent storage and are also academically interesting: The "concept" of memristors was explored over 50 years ago (they are passive components that couple electrical charge and magnetical flux, just like a resistor does with current/…

Is that actually the case? Or have memristors just proven to be a 'boring' technology that's just quietly replaced other bits and pieces that we don't hear about? A bit like graphene was supposed to be this wonder material, and now it's found in the soles of trail and hiking boots.

Nit: we take 20w of chemical energy not electrical one like computers, way worse efficiency compared to solar panels Id say

That's why the most efficient use of Superman would be to turn a giant crank generating energy

And it's EoL after about 40 years too.

The original pre-print is available at: https://www.researchsquare.com/article/rs-3647379/v1 which is probably a less spammy source than the ResearchGate link.

What's wrong with Research Gate?

What value does it provide over linking to the original source?

Any website that constantly asks me to login is spammy in by book. It's a for profit website that adds little value other than duplicating information from primary sources and occasionally mangling pdfs with redundant information to advertise themselves.

They also provide a central place to search things, with a richer interface than Google scholar, and have centralized a significant amount of good sources.

There's a reason millions of researchers have joined. That you don't find value or know what they provide is no reason others should not learn the value they add.

As far as I know, they have no application apart from academic toy/reseearch subject right now. And you have to consider that there are a lot of niches for storage technology that they could have taken over (because there is a lot of tradeoffs to make, e.g. latency, bandwidth, persistence, density, power consumption).

We might be just a few breakthoughs from those things replacing flash memory in SSDs, or revolutionizing neural-network accelerator hardware, but I am quite skeptical for now.

Note: I still believe that this (and other stuff i'm skeptical about) is SUPER worthwhile to research and always a huge uphill battle, simply because we have invested hundreds of billions of dollars into improvements of CMOS technology and processes, and collected over half a century of experience with it...

But new tech is to me kinda like a startup-- not every technology is the future, just like not every startup is a unicorn. Investing is still the right move, but you have to be realistic about expectations (which modern media is absolutely not)

I'm surprised they chose Researchgate to publish their pre-print, instead of Arxiv

Our current society converts chemical energy to electrical, not the other way round. So its the electrical energy user that needs a lossy conversion step.

Fossil fuel plants are chemical -> heat -> mechanical -> electrical. The heat -> mechanical step is the inefficient one, sadly limited to ~40% efficiency even with very fancy machinery. Most other conversions can be above 90% efficient.
