I think decentralization will be a bigger theme in the next decade. Crypto nerds got a huge amount of surprise money in 2017 and the smart ones seem to be taking advantage of it. Even if only a small fraction of those are pursuing worthwhile projects I think the stage is set for a wave of "surprise" upsets 5-10 years down the line. The biggest will get bigger in that time as well, but they'll also be reaching the age where they start slowing down and turning consumers off with out-of-touch decisions.
