Re: Tool For All??
"There can be no tool that works for all computing applications."
I seem to recall from my 3rd year course on computation complexity in my maths degree at Oxford many years ago that a one-tape Turing machine sufficied for pretty much everything (so long as you had enough time and a long enough tape!) ... and there was a time when, I assume, I would have been able ot remember how to prove that this was correct.
