RPN calculators are still being sold by HP. This includes financial, scientific, and graphing calculators.
The current RPN HP graphing calculators leave a lot left to be desired, and aren’t as good as the old ones. I have an HP 50g RPN graphing calculator which is amazing. But, there are even better ones that are no longer in production.
Swiss Micros makes remakes of such amazing HP calculators: https://www.swissmicros.com/products
At some point I will purchase the DM41X from there.

Yeah, I had a HP-48 during my uni years. An awesome machine.

Also, fewer keystrokes, no?

Depends on what you are doing, but it can be fewer keystrokes for more complicated calculations, aka not basic arithmetic like 33 x 42, which is six keystrokes either way (3,3,x,4,2,= or 3,3,Enter,4,2,x).
Edit: replaced asterisks as multiplication symbol for x’s to avoid markup processing.
But author of the video was surprised that the calculator was using Reversed Polish Notation(RPN). Hewlett-Packard (HP) produced a whole line of calculators that also used RPN. It is a pretty smart idea to use on calculators where there is not a lot of memory available.
