All engineering fields are either solutions looking for problems or problems looking for solutions.
The secret of doing many things at the same time is to do them all poorly.
Forecasting the future of technology is risky. Predictions tend to be linear whereas technical advances come in quantum jumps from paradigm shifts. After the second World War, forecasters in electronics [who did not foresee the transistor] would have linearly [and incorrectly] foretasted breakthroughs in better vacuum tube reliability from, for example, improved filament chemistry.
