| Well, in physics we compute the speed with half life of what we want to keep alive regarding the costs. Mass transportation is an example of industry where half life is decades/century. Fast for this sector is slower than what the life expectancy of a coder represents. Games made to support a product ad are ephemeral, 1 month. Faster than a new release of firefox. Some dangerous radioactive isotopes are 10000 years. So nuclear plant related automation should not be using any CPU. A citizen data should last for the government as long a citizen live. Government if they aim at remaining stable should consider the half life of their automation to be long, way long. Hence slow changes. Very slow So do banks. But banks have to adapt with the speed of trades. Fast and slow can be set by doing something agile hates: careful business analysis. The problem is how we coupled all the businesses with insane costly rhythm that are forced down on every economical activities by the mean of noncompetitive business practices. Like useless obsolescence driven by HW monopolies, cheap energy, cheap regulated and poor education. Do we really need 1 Pb hard drive when entropy predicts we will not be able to find any relevant information given we have to much data without increasing the means involves in costly ways? We don't need fast changing technologies, we need boring, slow changing technologies that are reliable. |
