Interesting read.

I've been programming since the mid 70's (started with a 2650 and TI59).
Graduated in Computer Science and mathematics in 1984, did Honours in
Computer Science in 1985.

Fast forward decades and I completed a Masters in Astrophysics and a Ph.D.
in astrophysics as well.

Hate Fortran and Cobol, but can program in 15+ languages and am especially
good at C.

But, here's something interesting. I picked up R during my Ph.D.

I'm now paid professionally to program in R.

R is *different*. Every variable is a vector. Even if it's a million rows,
a billion rows - that's fine. You have to think differently. Despite all my
experience, this is now one of my favourite languages.

Statisticians embraced R decades ago. Every statistical test is freely
available. Need to do Allan variance? It's done. Need to do a Lomb-Scargle
periodogram? Done. Combine that with publication quality plots as well.

I think time-nuts should have a serious look at this language. It's
available on all platforms for free. RStudio is what you need to look for.
