Cleo Abram interviewed Demis Hassabis (CEO Google Deep Mind)

I’ll follow up here with thoughts, as I make my way through. Clearly it’s going to be a good interview.

The COSMAC 1802 microprocessor (1976) had approximately 5,000 transistors, and 16x16-bit internal registers. The MOS 6502 (1975) had even fewer transistors, yet went on to power most of the early PC era.

A human brain weighs 3lbs and draws 30W.
Perhaps we're scaling in the wrong direction.

The Jupiter ACE was built by two ex-Sinclair engineers who helped design the ZX Spectrum β€” the only home micro to run FORTH! The archive preserving its legacy needs support. Help keep this Sinclair heritage alive! πŸ•ΉοΈ www.jupiter-ace.co.uk/

When I was a student, Alan Winfield, one of my lecturers started up a spin-out company to create a fast hardware Forth processor.

"The Wizard of Oz" (1939).
A tale of snake oil, flimflammery, androids, witchcraft, lies about the nature of true intelligence, lots of wind.
It had it all.

If your pop-sci book shelf is looking for a new addition - Emma Chapman's Radio Universe is coming out this week. It's genuinely delightful and well worth picking up a copy!

Interesting new M dwarf #exoplanet occurrence rates paper! I'm glad to see that the new TESS result (with much lower uncertainties) is consistent with our Kepler result!

I was curious to figure out what the beefiest single board computer under $30 is (AKA C$40). The first real standout is the Radxa Cubie A7Z. The model with 1 GB DDR4 meets that. Features an Allwinner A733 SOC: 8 CPU cores, PCIe 3.0, WiFi6+BT5.4, RISC-V coprocessor. 🀯

Also available with 2/4/8 GB.

An abstract representation of the #LEGO mindset has been available as a programming language since 1970.
It's called #FORTH.

Planetary-scale Rube Goldberg machines may find occasional nuggets by sifting through Humanity's accumulated wisdom, but at what cost? Especially if one of those costs is the vast dumbing-down of people Γ  la "Brave New World". A human mind uses tens of watts, not billions.

"I much prefer the sharpest criticism of a single intelligent man to the thoughtless approval of the masses"
- Johannes Kepler

This might be applied to AI as well as to 'the masses', especially the 'thoughtless' part.

With the crazy jump in RAM prices, the #RetroComputing community might do well to make adapters for using old memory in new computers, if that's possible.

πŸ₯³ Major milestone for the 🏴󠁧󠁒󠁳󠁣󠁴󠁿Scottish Dark Sky Observatory: architectural designs are now public and isn't she a beauty! Two 5m πŸ”­domes, observing deck, solar-panelled planetarium, exhibition area & cafe.
Fingers crossed that planning permission gets approved!

In the early 1980s, ordinary citizens had access to real computing. Ubiquitous computational thinking was within our grasp. But sadly, the world fell into decades of sifting eye candy, and eventually became a wasteland of zombified slopchuggers.

Alas, what might have been.

A mini setup on the bench today, I needed to do some PET stuff and my main bench is full of a different project.
One of the first batch of SD2PETs (2019).
The first Mini PET (2020).
The first Deluxe Keyboard (2020).
Definitely not the first mini LCD from Amazon (2024).
All still working nicely.

I miss when the OS was a self-contained tool rather than an internet service. We had to manually configure the date and time, which was a small trade off in exchange for the independence.

Modern A.I. research bifurcates into generative and sensorimotor. The latter is often a euphemism for #GOFAI that transforms gauche into chic and minimizes the eye-rolls I get at klatches and seminars (attending, not speaking).
