Nope, Computers almost certainly *are* responsible for the use of the
asterisk for mutliplication - not because of confusion, but because
there was only so much room in early character sets and × and ÷ didn't
make the cut. But in typeset mathematics books long
before computers, multiplication was indicated by either simple
juxtaposition or a dot. As I said, I've personally never seen
× and ÷ anywhere other than in early-grade workbooks and on calculator
keys.
