The situation in AGI seems akin to that in space science, where many
well-trained researchers in the field tell us that there is no future in
human space flight, and that we should limit our dreams to unmanned
exploration.

Can anyone suggest historical examples of fields where almost none of the
scientific or engineering establishment would accept the possibility of a
breakthrough, which nonetheless soon came?

What was the situation in nuclear physics in 1935, before the great advances
towards the Manhattan Project, or in fluid physics and mechanical
engineering in 1895, before the Wright Brothers? Or can someone give some
other cases? I am not referring to the usual quotes from isolated skeptical
senior scientists, nor to dismissiveness from the lay population, but to a
situation where the entire field ignores an upcoming breakthrough.

And conversely, what is an area where an entire field recognized the
possibility of revolutionary change, which in fact came? General computing
of the last 60 years? Spaceflight engineering in 1953?

Ben,

I think these things go in cycles.  AI had its time of big funding, but
that didn't produce much and so it stopped.  The impression I get with
string theory is that pressure is building up to cut it back unless it
comes up with better results.  At least in the case of string theory
they can produce lots of fancy mathematics which counts as a kind
of "evidence", or more accurately, it makes it count as "serious science".

With the Genome project at least it was clearly a finite goal that would
eventually be achieved.  Funders like that because they feel confident
that what they are funding will eventually be done.  With AGI, well a lot
of people still seem unsure if it is even possible, and if it is then it
might
happen in a few hundred years.  Funders don't like that story much.

Of course some of us believe otherwise...

Shane
