 Theobald questioned and criticized conventional confidence in economic growth, in technology, and in the culture of materialism - all of which he considered to be damaging to the environment while failing to provide opportunity and income for many of the world's people.He warned against trying to maintain, and to spread or mimic worldwide, the American standard of living of the late 20th century.Despite his criticism of some aspects and effects of technology, Theobald saw tremendous potential in communications technology like on-line, personal computers (which in the 1980s he termed "micro-computers"), seeing these as tools for pooling the thoughts and opinions of very large numbers of individuals spread widely, geographically.
