> Is there a better estimate of total value this can create?
I don't think there'll be a way to realistically estimate this for at least another decade. That would be like asking what the effect of TCP/IP will be on eCommerce in 1980. What I've laid out is very, very high level, while the technology is still in what could be considered pre-alpha stages.
The big four accounting firms bring in about $40 billion in revenue each. Thus $160 billion would seem to me to be a reasonable order of magnitude estimate for the max value audit-free fin-tech can create.
Is there a better estimate of total value this can create?
