I grew up reading C.S. Lewis and his Narnia Stories.
And at that time I didn't get what was going on - I think it was when finally I was reading
one, I then started thinking 'this seems like an allegory' and then sort of realising 'a
christian allegory' and then I felt 'oh dear!'.
I had to of course read all of them.
In the end I was quite cross at Lewis for trying to foist that kind of stuff on children.
He of course was unashamed - he was arguing in his letters 'of course, if you are a christian
you should make christian stories and try to tell them' - but then of course he hides
everything - so instead of having Jesus he turns him into a lion and so on.
But there's an interesting problem in general of course 'where do we get our ideas from?'.
I grew up in boring Sweden in the 70's so I had to read a lot of science fiction in
order to get excited.
That science fiction story reading made me interested in the technology & science and
made it real - but it also gave me a sort of libertarian outlook accidentally.
I realised that well, maybe our current rules for society are arbitrary - we could change
them into something better.
And aliens are people too, as well as robots.
So in the end that kind of education also set me on my path.
So in general what we read as children effects us in sometimes very subtle ways - I was reading
one book about technologies of the future by a German researcher - today of course it
is very laughably 60ish - very much thinking about cybernetics and the big technologies,
fusion reactions and rockets - but it also got me thinking about 'we can change the world
completely' - there is no reason to think that it works out that only 700 billion people
can live on earth - we rebuild it to house trillions - it wouldn't be a particularly
nice world, it would be nightmarish by our current standards - but it would actually
be possible to do.
It's rather that we have a choice of saying 'maybe we want to keep our world rather small
scale with just a few billion people on it'.
Other would say 'we can't event sustain a few billion people on the planet - we're wearing
out the biosphere' - but again it's based on a certain assumption about how the biosphere
functions - we can produce the food more efficiently than we currently do.
If we went back to the primitive hunter gatherers we would need several hundred earths to sustain
us all simply hunter gatherers need enormous areas of land in order to get enough prey
to hunt down in order to survive.
Agriculture is much more effective - and we can go far beyond that - things like hydroponics
and in-vitro meat might actually in the future mean that we would say it's absolutely disgusting,
or rather weird to culture farmland or eat animals!
'Why would you actually eat animals?
Well only disgusting people back in the stone-age did that'.
In that stone age they were using silicone of course.
Dividing history into ages is very fraught because when you declare that 'this is the
atomic age' you make certain assumptions - so the atomic age didn't turn out so well because
people lost their faith in their friend the atom - the space age didn't turn out to be
a space age because people found better ways of using the money - in a sense we went out
into space prematurely before there was a good business case for it.
The computer age on the other hand - well now computers are so everywhere that we could
just as well call it the air age - it's everywhere.
Similarly the internet - that's just the latest innovation - probably as people in the future
look back we're going to call it something completely different - just like we want to
divide history into things like the Medieval age, or the Renaissance, which are not always
more than just labels.
What I think is unique about our era in history is that we're very aware that we are living
in a changing world; that is not going to be the same in 100 years, that is going to
be utterly utterly different from what it was 100 years back.
So many historical eras people have been thinking 'oh we're on the cusp of greatness or a great
But we actually have objective good reasons for thinking things cannot remain as they
There are too many people, too many brains, too much technology - and a lot of these technologies
are very dangerous and very transformative - so if we can get through this without too
much damage to ourselves and the planet, I think we are going to have a very interesting
But it's also probably going to be a future that is somewhat alien from what we can forsee.
If we took an ancient roman and put him into the modern society he would absolutely shocked
- not just by our technology, but by our values.
We are very clear that compassion is a good virtue, and he would say the opposite and
say 'compassion is for old ladies' - and of course a medieval knight would say 'you have
no honor in the 21st century' and we'd say 'oh yes, honor killings and all that - that's
bad, yeah actually a lot of those medieval honorable ideals they're actually immoral
by our standards'.
So we should probably take that our moral standards are going to be regarded by the
future as equally weird and immoral - and this is of course a rather chilling thought
because our personal information is going to be available in the future to our descendants
or even ourselves as older people with different values - a lot of advanced technologies we
are worrying about are going to be wielded by our children, or by an older version of
ourselves in ways we might not approve - but they're going to say 'yes but we've actually
figured out the ethics now'.
The problem of course of where ethics is ever going is a really interesting question in
itself - so people say oh yes, it's just relative, it's just societies making up rules to live
by - but I do think we learned a few things - the reduction in violence over historical
eras shows that we are getting something right.
I don't think that our relatives could just say that 'violence is arbitrarily sometimes
good and sometimes bad' - I think it's very clearly a bad thing.
So I think we are making moral progress in some sense - we are figuring out better ways
of thinking about morality.
One of the interesting things about our current world is that we are aware that a lot of ideas
about morality are things going on in our culture and in our heads - and are not just
the laws of nature - that's very useful.
Some people of course think that there is some ideal or best moral system - and maybe
there is - but we're not very good at finding it.
It might turn out that in the long run if there is some kind of ultimate sensible moral
- we're going to find it - but that might take a very long time and might take brains
much more powerful than ours - it might turn out that all sufficiently advanced alien civilizations
eventually figure out the right thing to do - and do it.
But it could also turn out actually when we meet real advanced aliens they're going to
be as confused about philosophy as we are - that's one of the interesting things to
find out about the universe.
