I am sorry- the technology exists to make plastic shakuhachi that play li=
ke=20
the best. (Assuming the 'the material doesn't matter' theory is true.) I =
am=20
typing this email on a laptop with a much higher degree of exactitute in =
its=20
parts than any shakuhachi. It is just a matter of time to an industrial=20
engineer turns his eyes onto a shakuhachi...
