Every one of these entries is wrong, in some degree. Verne was not the first writer to imagine a voyage to another world by some mechanical means, Asimov was not the first to write about mechanical humanoid robots, Huxley was not the first person to think of duplicating people, the internet was written about long before brunner and gibson, Brin was generations late in predicting hyperlinks and WWW, the entry on webcams is nonsense because it contains no specific information, Heinlein did not invent the waterbed, nor is the reference cited by him even his earliest, Clarke was not the first to think of comm satellites (although he did think of the idea of geostationary satellite networks), clarke was not the first to describe space tourists, and microsurgical instruments were correctly described by another sf writer long before fantastic voyage. I like your blog, but don't waste everyone's time printing this poorly researched crap.
