"Michael the problem is not that the ad tech industry is not worth. The problem is that precisely because serious engineers are not dedicating and controlling enough of the innovation that we re ending up with a loop of low added value chains. Precisely i would argue the opposite: more engineers should start new ad tech firms. There are enough examples of very successful ad tech firms out of israel to point that this is something possible. The problem is the lack of innovation: not the lack of interest for a potential trillion dollar industry" - Ouriel Ohayon
