Fast forward 30 years, mix in global warming, govt funding of competitors (Etihad), oil price rises and good theories have of often been proved wrong.
Looking ahead how can I know if in 20 years I'll be driving an oil fuelled car to work, an electric car to work or staying home to work cause my virtual office is just as efficient.
My good theory, which may well be proved wrong, is that there is almost NO way that you will be driving an oil fuelled car to work in 20 years, NO way.
