I saw a very interesting info graphic here. Showing how vc funds are distributed across industries (2014 - 2015). Now, assuming that education increases productivity while social media and advertising decreases productivity via multiple distractions we can predict that productivity trends are mostly downwards - worldwide.
Note that this hugely unscientific prediction does not take into account overlap ( communicating with experts on social media ). Plus you could argue that the massive investment in business and financial technology should have a positive productivity impact. But I would argue that these are tool improvements and the skills required to make the best use of those tools may not be transferable. The 'worldwide' part points back to the title. Developers usually follow the money.
Final note, hope to be proved wrong on this prediction
