Previous: What Singularity? Yesterday I took issue with Alfred Nordmann’s IEEE post in which he claimed that technological progress was slowing down instead of accelerating. I claimed instead that it was being distorted by the needs of the next rungs of the Maslow hierarchy, and that a huge portion of society’s energy was going into… Continue reading ESP

Proteins

If you were an alien from an advanced civilization who had been stranded on Earth, but had all your people’s knowledge on a thumb drive, how would you go about creating nanotech and building up Earth’s technology to the level you could rejoin your galactic civilization? If you actually knew the details, probably one of… Continue reading Proteins

Good enough … intelligence

A couple of bloggers have noted the article at Wired about the Good Enough “revolution.” After some trial and error, Pure Digital released what it called the Flip Ultra in 2007. The stripped-down camcorder—like the Single Use Digital Camera—had lots of downsides. It captured relatively low-quality 640 x 480 footage at a time when Sony,… Continue reading Good enough … intelligence

The Black Box Fallacy

Consider this marvelous story by Richard Feynman: (watch it now, this won’t make too much sense otherwise) Feynman and his friend John Tukey discover that they have completely different internal ways of thinking, or at least of counting, even though they are using the same words to talk about what it is they’re doing. Consider… Continue reading The Black Box Fallacy

Singularity or Bust

It’s a question of some interest whether the Singularity will consist of just more exponential growth, or whether some superexponential growth mode is likely to happen (or is even possible), such as would be required for a real mathematical singularity. On the side of exponential growth, as I pointed out here, is the fact that… Continue reading Singularity or Bust

Education

There’s a very nice post at IEET by Marcelo Rinesi entitled Education and Learning: Still in the Middle Ages. He points out that we’re pretty damn bad at education compared to the improvements we’ve seen in most other endeavors: Our lecture halls are better than those of the Middle Ages, our textbooks friendlier than those… Continue reading Education

A cautionary note, concluded

Last week I posted a story of strange behavior in the simulation of molecular machines. One commenter asked if this was due to something unusual in the starting configuration of the atoms. This was the first thing we investigated, and didn’t seem to be the case. There was a small amount to strain energy in… Continue reading A cautionary note, concluded

A cautionary note

One of the constraints laid down by DARPA at the recent Physical Intelligence proposers workshop was that the model of intelligence that was to be proposed had to have a physical implementation. It seemed odd to some of the attendees that this should be a hard constraint, since many models of intelligence have a perfectly… Continue reading A cautionary note

Negative resistance

If you connect a 12-volt battery to a 4-ohm lamp, 3 amps of current will flow through the circuit by Ohm’s Law, V=IR. Power = VI = 36 watts will be dissipated by the lamp. If you add a 2-ohm resistor in series with the lamp, the resistances add to 6 ohms, the current is… Continue reading Negative resistance

Do the math

There is at Technology Review’s arXiv blog an article “How to find bugs in giant software programs.” It’s an overview of a paper on arXiv which is a statistical study of program sizes and bug distributions in the Eclipse dataset of Java programs. TR says, So how are errors distributed among these programs? It would… Continue reading Do the math
