Naturally, virtual reality is not without controversy. One was legal: what if you offer a product, like a head-mounted display, that encumbers a person's sight? Are you liable when they trip over a chair? Our legal advisors said "Yes"!

What if you trademark a public word, such as Cyberspace? Our advisors said "That's OK".

I feel strongly about this: if you intend to define an idea

about technology, you should at least have had some experience with the technology. To some, Cyberspace is a cultural idea, divorced from any technological manifestation. NOT!

These pieces represent my cultural commentary, in the form of reviews of other folks work, and highly speculative articles designed to test the limits.
