I'd like to ask some opinions about something that's been on my mind recently.
Within the next thirty years, plastic will probably be the most expensive component in computers or tech-devices due to petroleum prices and shortages. Whilst I can envisage us getting power for transport and electricity from another source (such as nuclear), I can't see what will replace oil-based polymers, especailly as there is so little time to develop something completely different? Most plastics are thermosetting and cannot be recycled like thermoplastic can, so it's not just a case of having a good recycling program, as we can for aluminium.
It's scary to think that within our lifetimes, after struggling to get technology into schools, that they may have to regress to pencil and paper. It's even scarier that I may not have a computer during my retirement - what would one do all day?!
