I do think that working with more primitive languages gives you some insight that higher level languages do not. Assembler was essential at one time, even on mainframes. Not something that you used all the time, but something that you needed to know.

(I remember asking a younger, but very versatile programmer with a problem about "one's complement" and getting a blank look in return. But for that particular bug, it was essential to understanding the problem. (This was a bug with SQL Server, bcp, and datetime data from version 6.0 or 6.5.))

Anyway, regarding C, my oldest extant program was written in C about 29 years ago. Still running today. Ha.
