The final episode of readings from "The Science of Can and Can't" by Chiara Marietta. This serves as something of a summary chapter with pointers about the future of Constructor Theory.

A version of this on Youtube has music and images as a farewell finale to the "Things that make you go mm?" series. This is about meaning: what is it, is there a meaning for us? Does the question make sense?

Rational and anti-rational memes.

Static and dynamic societies.

Diversity of ideas and individuality.

Minds are the makers of memes; ideas that survive. But how is it memes are replicated and transmitted through a culture? What counts as a meme?

The crucial differences between AGI and regular AI: minds vs the mindless. Is "competency" at completing tasks what makes a system "intelligent". I explain why that is, in a deep sense, the opposite to what intelligence may be - or at least the kind of intelligence that is interesting in the I in AGI.

What is a mind? Can we pin it down? To what do the pronouns "I" and "you" really refer? Is the mind different to its contents? What do we know and what are we struggling still to understand?

Stability under rapid change - progress - has happened rarely in history. It has been sustained only once. In any case it began in Britain? Why? We cannot articulate all the reasons, much of that content remains inexplicit. But we cannot ignore systems of governance - and in that case the constitutional monarchy.

What is metaphysics? Is there a point in subscribing to one? Some think believing in certain theories about the way ultimate reality must be is helpful. How is a metaphysical stance consistent with both realism and fallibilism? 

In his book "Our Mathematical Universe" Max Tegmark claims we occupy 4 different kinds of multiverse and that ultimate base reality is made of mathematics. I analyse these claims and his 4 levels of multiverse distinguishing between scientific and metaphysical claims by describing possible experimental tests of some of the multiverses - and remark on this desire many express for an ultimate, final explanation of reality.

This continues the theme about fallibilism and is a brief recount of David Deutsch's insightful talk given at the award of the 2017 Dirac Medal - found here: https://www.youtube.com/watch?v=J7HeDX_7Heg&t=10096s (cued up to just before David begins speaking) or the transcript available here: http://www.daviddeutsch.org.uk/wp-content/uploads/2018/03/MathematiciansMisconception.pdf This is a very "counter-culture" idea (academic culture, that is) and I feel I get more resistance to this idea than even, for example, The Multiverse.
