I also recently read a book I'd been saving for 50 years..."Towards the Year 2018" that I bought in 1968. A group of futurists took a look forward 50 years to give a prediction of what today would look like. Some of them were insightful and pretty accurate if not exact...some of it was hilariously wrong.
A couple of the big things they got wrong were weaponization of the weather, the ability to generate hurricanes and throw them at enemy naval forces...and personal travel by ICBM (!?!)
