No, because they address different concerns. Depending on the project
one may have occasion to use SPI, I2C or both.

If you want to hook up a small, fixed number of peripherals to a
microprocessor then SPI is much simpler to use. If you want to hook up
a large number, or an unknown number, of peripherals to a microprocessor
then I2C can't be beat.

Of course sometimes you have a peripheral that you must use that only
comes with one interface, and then you're stuck.
