Have you paid no attention? Falsifiability was never a concern even
before Cantorian Set theory , nor can it ever be a concern outside the
scientist's modus operandi , into mathematics by itself, without the
Physical world on which to perform experiments . Going by your
'operational' usage of falsifiability, I would classify it as "not
even wrong" , to use an expression preferred by scientist .
Mathematics is about rational proof . Physics today is about disproof
of an endless stream of hypothesis .
