Ochre Insider,
So what you are suggesting is that I should just say, "oh well I MIGHT not have a career in 30 years time so, ah stuff it I'll go and do another job somewhere where it's guaranteed I won't be made reduntant in 30 years time."
I highly doubt a job like that exists. Since the Industrial Revolution technology has increased exponentially, and I beleive that it will continue to do so.
You say that oil will become prohibitively expensive and everything will be doom and gloom. well they said this at the last oil crisis, and now it's being sued more than ever.
In another 30 years who's to say that jet engines will be powered by crude oil derived products anyway.
I for one don't want to be of those people that looks back and thinks "I wish I would've done this, I wish I would've done that."
