- 4. 4 of 23 Moore’s Law: c1965 § “Moore's Law” was coined by Carver Mead in 1970, from Gordon Moore's article in Electronics Magazine 19 April 1965 "Cramming more components onto integrated circuits“. “The complexity for minimum component costs has increased at a rate of roughly a factor of two per year ... Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years. That means by 1975, the number of components per integrated circuit for minimum cost will be 65,000. I believe that such a large circuit can be built on a single wafer” In 1965 he was designing ICs with ~80 transistors! And basing his observations on 30-40 transistor ICs!

We are not financially valuable to society. § Stage2: We learn from Teachers; and progressively know as much as most people (Secondary Education) § Whilst realizing there are others who know more, and less. § We are the sum of our Education; and on a par with most others. ... We are no more financially valuable to society than the next person § Stage3: We learn from Experts; and soon know more than most people in some areas (Tertiary Education) § Though in other areas we will know less than our peers § We are the sum of our Education; so could be replaced by another with similar Qualifications ... If our skills are needed; we are more financially valuable to society than the average other person. § Stage4: We learn from Peers and from our own Experience (Professional Education) § We are greater than our Formal Education; we cannot be replaced by another with the same Education profile. Formal Qualifications no longer define the role. § Professional Skill emerges as we develop the ability to identify and deploy subsets of what we know, in conjunction with what others know. Whilst our domain-specific knowledge grows, aspects of our Formal Knowledge may stagnate or decline. ... We are valued more highly (subject to demand), because we know what/how-to-do; though are frequently not best at doing specific things. ... Maintenance of Your Stage4-Value is (should be) an important part of Your Career Plans.

So … § Don’t be afraid to admit it, when You Don’t Know … You will always be part of a Team trying to make (Technical) Order out of Chaos! § Go to meetings to Contribute what You Know, to overcome the Team’s Challenge … Strive to Acquire New Knowledge for Yourself at every one Get yourself invited to the next § Remember that Successful End-Products pay for Everything in the/their life-cycle … Nobody, Scientist or Engineer, lives in a protected bubble! (Don’t forget this) § Learn to See/Recognise the change happening around you … It takes practice, but look around and see what has changed for you every year … Embrace the uncertainty of Challenge and Change … … It is your job to Deliver the Extraordinary!
