Hits and MITS

I just came across the following scan that describes how an MITS Altair 8800B became my first personal computer, journeying from Albuquerque to Las Cruces, New Mexico and getting an EEPROM burner attached to a ribbon cable snaking out through the enameled steel case. The speech synthesizer predated stored digital samples, by the way, so it instead emulated phonemic mixtures generated by digital waveform filtering.

And that young chap on the left would later become my boss, three or four parts removed, at Microsoft. I still have that Altair, too, safely stored away.

Towards an Epistemology of Uncertainty (the “I Don’t Know” club)

space-timeToday there was an acute overlay of reinforcing ideas when I encountered Sylvia McLain’s piece in Occam’s Corner on The Guardian drawing out Niall Ferguson for deriving Keynesianism from Keynes’ gayness. And just when I was digesting Lee Smolin’s new book, Time Reborn: From the Crisis in Physics to the Future of the Universe.

The intersection was a tutorial in the limits of expansive scientism and in the conclusions that led to unexpected outcomes. We get to euthanasia and forced sterilization down that path–or just a perception of senility when it comes to Ferguson. The fix to this kind of programme is fairly simple: doubt. I doubt that there is any coherent model that connects sexual orientation to economic theory. I doubt that selective breeding and euthanasia can do anything more than lead to inbreeding depression. Or, for Smolin, I doubt that the scientific conclusions that we have reached so far are the end of the road.

That wasn’t too hard, was it?

The I Don’t Know club is pretty easy to join. All one needs is intellectual honesty and earnesty.… Read the rest

Singularity and its Discontents

Kimmel botIf a machine-based process can outperform a human being is it significant? That weighty question hung in the background as I reviewed Jürgen Schmidhuber’s work on traffic sign classification. Similar results have emerged from IBM’s Watson competition and even on the TOEFL test. In each case, machines beat people.

But is that fact significant? There are a couple of ways we can look at these kinds of comparisons. First, we can draw analogies to other capabilities that were not accessible by mechanical aid and show that the fact that they outperformed humans was not overly profound. The wheel quickly outperformed human legs for moving heavy objects. The cup outperformed the hands for drinking water. This then invites the realization that the extension of these physical comparisons leads to extraordinary juxtapositions: the airline really outperformed human legs for transport, etc. And this, in turn, justifies the claim that since we are now just outperforming human mental processes, we can only expect exponential improvements moving forward.

But this may be a category mistake in more than the obvious differentiator of the mental and the physical. Instead, the category mismatch is between levels of complexity. The number of parts in a Boeing 747 is 6 million versus one moving human as the baseline (we could enumerate the cells and organelles, etc., but then we would need to enumerate the crystal lattices of the aircraft steel, so that level of granularity is a wash). The number of memory addresses in a big server computer is 64 x 10^9 or higher, with disk storage in the TBs (10^12). Meanwhile, the human brain has 100 x 10^9 neurons and 10^14 connections. So, with just 2 orders of magnitude between computers and brains versus 6 between humans and planes, we find ourselves approaching Kurzweil’s argument that we have to wait until 2040.… Read the rest
