I think he is confusing knowledge with skill.

My knowledge gets outdated: APIs change, the top of the hour is a different one.

Skills and especially abstract skills don’t get outdated as fast: Writing cuda kernels is surprisingly like the stuff we did in my first ever C class 25 years ago and I am still reading doc the same way my teacher taught me in 7th grade.

The more you look the more things are the same. All that is done was done and has been done before; there is nothing new under the sun.

Does math fall into skills or knowledge? I think it falls into knowledge. Math never goes obsolete.

It is similar to programming or software in that it involves both skills and knowledge. But the knowledge doe not quickly become obsolete. If you think about it, just about every activity involves both knowledge and skill. There are also different depths to knowledge. The knowledge required to be functional in a field may not be the same level of knowledge required to advance that field.

I think there are skill and knowledge components to math—skill at manipulating equations, knowledge of theorems and identities. These play into each other, of course.

[niemandhier]

I think advanced math is a form of art.

Not all knowledge. Basic POSIX knowledge should serve you for a long time
