Too far out weird and unrealistic for a serious essay
Definitely
I think they are looking for something more specific than revolutionizing technology :P
No seriously, you need to write this in the conventional way. Those guys probably want to see how you do the homework on the university and the department, your knowledge on the courses being taught at the department, etc.
Just out of interest, why do you want this
I want the effects of pressure to remain constant, in whichever environment we're in.
I think a lot of people would be out of work if that were to happen ;)
