Poor logic. The algos get shared and replicated, especially given open source. For example: http://www.vanityfair.com/business/2013/09/michael-lewis-goldman-sachs-programmer http://www.vanityfair.com/business/2013/09/michael-lewis-gol... The algos can be created by fewer people. Traders are being replaced by the algos, and fewer people are required to create the algos than do the original trading. So your point does not have a 1-to-1 job creation-destruction ratio.
