in the 20th century lots of new material
its importatnt to study the room to grow in every subject
and to constrast the positive space of what is know
with the negative space of what is not
most expertise is simply the ignorance of the unlearned
who hold certain people on pedastals because they don't
know better...think of doctors in the pre-civil war days
would the be considered "experts" today? highly questionable
yet they were the best resources that time/place could muster
every startup is exploring negative space in the market...that's growth potential
a new biz might be intelligent design, but that has nothing to do with evo bio
etc...
doctors are also scientists and biz people and human
And an 18th century doctors is no less a scientist because of his ignorance;
it doesn't make darwin a 'creationist' because he doesn't understand relativity or nuclear physics
obviously absurd example of course
