I can believe it.  I know driving has gotten safer in the U.S.
since I learned to drive (more recently than 100 years ago).

Sorry, I didn't mean for my silly joke to cause an off-topic discussion
about cars.

Probably not.  But note that the move almost entirely away
from assembly language reduced the number of lines of code
needed for a given functionality.  So we had to increase the
amount of useless functionality to make up for that.  ;-)
