Bash is not Bourne, and that's the point. Bash is the Bourne Again Shell, a shell written to improve and replace the Bourne shell in the GNU ecosystem. Modern bash is a huge improvement over the original Bourne shell and I'm convinced you use bash only feature basically every day, and would be very annoyed if someone forced you to use the actual Bourne shell
Ah, right! I do remember the original Bourne Shell, though. I wouldn't like to get back to using it. Though I might agree provided I get as many years of my age back.
