I think what's getting increasingly difficult is identifying what a "tech" stock is. Companies like Uber and AirBnb blur the line as their innovations are mostly not the silicon and CS kind but are about economics and working around regulations. It's easy to call Google a "tech" stock, but what about Netflix? At this point streaming technology is mostly commodified. Is Netflix a tech company or an entertainment company? I think a strong argument could be made for the latter. So saying that you should invest in "tech" stocks is increasingly ambiguous.
