Is RPN still relevant?

[Tugdual]

I still have faith in RPN to crunch calculations; I recently discovered RPL and found it extremely elegant and convenient for calculators. Now, even if it is possible, I don't think RPL is suited for very large apps to the point I wonder why the 50g is so big.
With the introduction of symbolic calculation, the use of RPN was naturally made obsolete. Still calculators have small keyboards and I simply don't think calculators are primarily designed for this usage, computers will do a much better job is all other cases. Calculators should remain simple tools used only for the sake of crunching quick calculations or coding some quick automation. For that reason, RPL and RPN have reasons to remain to the detriment of gigantic calculators which may disappears just like dinosaurs did.
