Oh god Craig Minns, you do carry on. Bet you believe wind farms grow wind.

When I was at school, 60 years ago, some clown careers advisor fed me the same rubbish. "be careful what you do, by your middle age computers & machines will do all the work, many will not have jobs, & no one will work more than 20 hours a week".

HA!

Yes some jobs like car manufacturing is much done by machine, but it has not changed the number of jobs. Instead of a couple of blokes sketching up a car design, & then building the thing in the shed as of old, today we have a cast of millions spending a billion dollars designing the thing, & setting up another billion dollar factory with it's robots & programs to build it.

Far from reducing labour requirements, it has increased the labour in starting to produce so greatly than one poorly accepted design kills a company.

We now work longer hours, & it is not as much fun.
