Ron,
Even if all of Cyc were made completely free, without spending more than
the 30M for the FO project, that would not solve the problem of developing a
community of users, though it might speed the process a bit. OpenCyc is
already free, but there is as yet no community of users developing open
applications that can illustrate how the ontology can be used. It would
still require an infusion of money to pay people to develop applications,
and also to develop the translations from Cyc-speak to the other ways
ontologists represent their information. I don't see any alternative to an
FO-like project to get a widely used common ontology as quickly as possible.
Of course we can wait a few decades and hope that another process will show
up. I see no virtue in waiting, since, as I have pointed out several times,
the losses due to waiting are much greater than the cost of the FO project. (01)
