“The Theological Objection”

This month’s post considers a little-remembered part of Turing’s otherwise famous 1950 paper on AI.

Just for once, this month, let’s not skirt around the generally problematic issue of ‘real intelligence’ compared with ‘artificial intelligence’ and ask what it means for a machine (a robot, if you like, for simplicity) to have the whole package: not just some abstract ability to calculate, process, adapt, etc. but ‘human intelligence’, ‘self-awareness’, ‘sentience’; the ‘Full Monty’, as it were.  Star Trek’s ‘Data’ if you like, assuming we’ve understood what the writers had in mind correctly.

Of course, we’re not really going to build such a robot, nor even come anything close to designing one.  We’re just going to ask whether it’s possible to create a machine with ‘consciousness’.  Even that’s fraught with difficulty, however, because we may not be able to define ‘consciousness’ to everyone’s satisfaction but let’s try the simple, optimistic version of ‘consciousness’ broadly meaning ‘a state of self-awareness like a human’.  Is that possible?

Known Unknowns

This month’s post may make a valid point.  Or it may not.  Or it may be impossible to tell, the concept of which itself may or may not make sense by the end of the piece!

How do we handle things we don’t know?  More precisely, how do we cope with things we know we don’t know?  All right then: how do we handle things we know we can’t know?

As is the nature of this blog, the examples we’re going to discuss are (at first, at least) taken from the fields of computer science and mathematics; but there are plenty of analogies in the other sciences.  This certainly isn’t a purely theoretical discussion.

On the whole, we like things (statements or propositions) in mathematics (say) to be right or wrong: true or false.  Some simple examples are:

  • The statement “2 > 3” is false
  • The statement “There is a value of x such that x < 4” is true
  • The proposition “There are integer values of x, y and z satisfying the equation x3 + y3 = z3” is false

OK, that’s pretty straightforward but how about this one?

  • “Every even number (greater than 2) is the sum of two prime numbers”

Seeing the Bigger Picture: ‘STEEPLED’ and ‘The Great Curtain’

Futurology is a difficult and inexact science, with a poor history of getting it right.  However, there are ways of giving yourself a chance or, at least, avoiding some of the more obvious mistakes and oversights.  This post looks at a tool for considering the bigger picture in futurology and reflects on the results of using it with various user groups.

We’ve made the point before that technologists aren’t necessarily (or solely) the best people to ask what the future may hold because:

  1. they only tend to think about technology, or
  2. when they think about things other than technology, they’re not very good at it.

Of course, there’s probably a parallel observation to be made about any focused specialist in a particular field (economists, lawyers, politicians, etc.) but the observation doesn’t invalidate 1 and 2: it just shares the blame around a bit.  So, what can be done to help, and where does it take us?

Santa in the Continuum

This year’s festive offering considers countable and non-countable infinities and follows (very) loosely from last year’s discussion of deterministic and non-determininstic optimisation

[Specially for Alex Irvine, who is either having trouble getting his head around infinite sets or still believes in Santa Claus: we’re not allowed to say which]

Father Christmas has a problem. The Intergalactic Department of Work and Pensions (IDWP) has threatened to cut his tax credits because he apparently only works one day a year. He’s tried to point out that he’s the head of a vast multinational organisation of elves and reindeer, who themselves work all year round, but that doesn’t wash with the IDWP boss, Ian ‘Dunkin’ Smiff, because his dad didn’t go to public school.

Planets

So, he’s been given extra work to do: a lot of extra work to do …
