At Large Companies, Fullstack Marketers Have The Power To Kill Agencies

The efficiency of fullstack marketers will make larger companies re-consider their current creation and implementation strategies. If small companies are doing an excellent job at digital marketing using only 1 or 2 marketers who can aptly execute on their own ideas, will it still make sense for a large company to have one team devoted to thinking up the ideas, and another devoted to executing and putting them into play on various marketing channels? It's been said recently that the marketing agency will soon die, but it's possible that there's a different future; one in which there are agencies of fullstack marketers, rather than teams, assigned to different company accounts.
