Moravac (in the linked paper): "In both cases, the evidence for an intelligent mind lies in the machine's performance, not its makeup." Do you agree? I'm much less keen to ascribe "intelligence" to large, pretrained language models given that I know how primitive their training regime is compared to a scenario where I might have been "blended" by their ability to "chat" (double quote here since I know ChatGPT and the…

This is reminding me again of The Bitter Lesson.

Quote from article At the present rate, computers suitable for humanlike robots will appear in the 2020s. Can the pace be sustained for another three decades? The graph shows no sign of abatement. If anything, it hints that further contractions in time scale are in store. But, one often encounters thoughtful articles by knowledgeable people in the semiconductor industry giving detailed reasons why the decades of phen…

Nvidia claims the H100 GPU can do >3e15 8-bit operations per second (3 billion - million instructions per second):

The promise of Instruction per Second scaling forever did stop being super-exponential. Instead of CPU based Instructions per Second we have continued scaling compute with GPU based Floating-point Operations Per Second which don't exactly have a 1:1 equivalence with instructions but are close enough. Nvidia released the "first" GPU in 1999 so it's not too surprising that this guy wasn't thinking in those terms in 1998. That's why Kurzweil and Bostrom used FLOPS in their extrapolations. They also end up in the neighborhood of 2020s/2030s in their later predictions in the 2000s.

With that in mind we are currently at 1 billion GigaFLOPS for the largest super computer in 2023. And the trendline since the 90's has kept up with the prediction made in the post. Although we can't exactly say 1 GigaFLOPS = 1000 MIPS.

> I don't know where to look to confirm that can current computers do 1 billion MIPS (Million Instructions per Second?) as predicted by this article?

An RTX 4090 has AI compute of up to 661 teraflops in FP16[1]. FLOPS and IPS are not interchangeable, but just for fun, that's 6.6 * 10^14 FLOPS, which is just short of 1 billion million (10^15).

Moravec's plots (from 1998!) are looking more and more like prophecies: https://www.jetpress.org/volume1/power_075.jpg https://www.jetpress.org/volume1/All_things_075.jpg

What I find incredible about the progress of computing power is that there isn't anything that actually makes Moore's law a given. Engineers keep discovering advances in materials science and manufacturing that enable advancements on such a consistent pace. Is this a fluke? Luck? What enables this?

M1/M2s are around 2-4 trillion if I’m not mistaken

not even within 2 orders of magnitude.

Reducing the capability of the human brain to performance alone is too simplistic, especially when looking at LLM's. Even if we would assign some intelligence to LLM's, they need a 400w GPU at inference time, and several orders of magnitude more of those at training time. The human brain runs constanly at ~20w. I highly doubt you'd be able to get even close to that kind of performance with current manufacturing proce…

Like, you know . . . nerve cells.
