He doesn't work with imaginary numbers, either. He treats complex numbers as matrices of rationals.
Which is the same thing for all intents and purposes.
An ultrafinitist is still allowed to call that 'i'.
Still kind of freaked out that a Möbius transform can be expressed as a matrix multiplication.
