Consequences of Moore’s law
1 Because of Moore law the ratio of price to performance of computers has fallen. For example the price of the standard computing device has fallen from around $4000 to something close to 1c for the same processor.
2 Because of Moore’s law the cost of data communication and data storage is essentially 0. Because there is basically no price on this technology there are wasteful and harmful aspects of business applications being developed then deemed useless and wasted.
