cryptography eliminates lawyers?

As a follow-up to the article reference I posted, I pose the following question: Will cryptographic technology and information (communication) technology reduce the need for legal services in the future? (especially regarding contracts, buying/selling, patent law, etc.) Will legal services just look different? Will they be more efficient (cheaper)? Put bluntly, will cryptography put lawyers out of business? Any comments would be appreciated. Cort.
