All Engineering Knowledge Has an Expiration Date. The Trick Is to Know When

IEEE Spectrum  August 23, 2019
According to the author as new knowledge accumulates, some old knowledge becomes irrelevant and falls off the knowledge stack. Almost all the college course work one took long ago is now useless in itself, although what remains is an engineering mind-set and a mathematical grounding. The purging of obsolete knowledge is probably insufficient to make room for the new stuff, as there seems to be an exponential increase in knowledge. The complexity of our work is always increasing, similar to the increase in entropy decreed by the second law of thermodynamics. Even as Moore’s Law wanes, the general law of exponential increase will continue the trend. As the new engineers come out of school, they are also empowered by the continual rise of new tools…read more.
