You didn't work back in the day when high end products where if you had to ask how much you couldn't afford it. In 1980 or so my office mate was working on a way to measure the efficiency of different toilet designs - to try and save water. I looked at using the then very new use of image recognition hardware (and I think neural nets) but sadly realised that with a base price of hardware at £250,000 around a million in todays money it wasn't practical. Which was a pity as the organisation was into ml/ai back then and even hired one of the first knowledge engineers (as they wher called back then).
