We have the luxury of hindsight to know which peculiar schools of thought were rubbish, so we don’t even teach them.

I’m sure there are many, many theorems built up with Euclidean Geometry that we don’t bother teaching anymore.

Because modern methods make the results trivial.

Today, what are we burdening upcoming scientists with unnecessarily?
