1969 lawrence g. roberts wrote a forecast about the costs of hardware and software replacement and how to calculate them. two years before he has written the first design paper on arpanet

Software Costs All of the conversion programming must be completed during the overlap period since it is usually unacceptable to suspend any portion of the work for more than a few weeks. In order for this to be true, the level of programming support during this time must cost at least A/m dollars per year. If m is less than n, this level of support would normally be retained until the next procurement cycle working on the new work. Some of the new work can be done during the overlap period, thereby eliminating some of the pure conversion workload. However, since rethinking the program takes longer than just recording it, the total overlap period workload would be increased, not decreased.(Data Processing Technology Forecast, April 23, 1969

another paper also including the costs, this time of delivering data

i have seen more stars in the eyes of engineers when they talk about machines and code then in the eyes of those sociologists, anthropologists and media analysts i met at pcst who talk about mankind.

there is less science coverage in media; science shouldn't be presented in a ghetto; but the studies/numbers they present to illustrate the downs and ups are taken from specific reportages de ciencia.

journalists are not trained as science journalists; let them study science journalism; they need to hold a degree; but if you are a trained academic, don't start in the science department, start to write in the chronic department because you don't know how to tell a story.

we have to bring science to the mass; journalists who are not scientists don't get it, they oversimplify; watch out if you use their material for education purpose; we are the specialists! jaja, then tell me your story right! and for god sake: can you smile while doing so?
