Question

1. With all those self-driving taxis scooting around, it would be nice if you could hail one just by giving the usual hand signal as it approaches -- rather than having to use a cell phone to make the pick-up request. You would like to build a system using a camera and quite a lot of image processing computation to recognize when a human is hailing. The currently best processor you can buy isn't fast enough to do this computation before the taxi has driven past the person who wanted a ride. Fortunately, your business plan says you don't need to ship your first product for two years. How would you go about figuring-out if fast enough versions of that processor will be available in two years when your product needs to ship? (Note: there are lots of valid answers to this question.)

Explanation / Answer

Looking at the rate of development in science and technology, it is ought to be developed in the two years. I feel the best possible way is to make sure the technology you develop now also accommodates the state of art after two years. No firm can wait for two years to know the technology and then build it's product. This can be best explained with the example of RAMs in Computers. Currently, most of us use 8gb RAM but they also provide us with another slot to make sure our needs are met even in future.
So, the best way would be imbibing the current state of the art on an Arduino board and give provision to include the state of art in the years to come.
Alternatively, a person can have a wrist band that sends IR rays and connects to the nearest Cab such that it haults after checking any close cabs.
