*Where is my flying car?: A memoir of future past*, by J. Storrs Hall

Who is this guy?  How come no one told me about this book until Adam Ozimek asked about it? One of the main arguments of the book is that we could have had major technological advances in multiple areas if only we had put in another fifty years of hard work on them.  Flying cars […]
