Immense food for thought.

Let's hope that at least some of the people elected to govern have began devising 99%-friendly plans for the major social changes that are coming.

There will surely be centers of power which will attempt to sustain the status quo, but how will the capitalist/consumerist model be able to continue existing when a huge percentage of the population won't be earning wages that would allow them to spend?

Unless everyone (regardless of their employment status) is provided a basic income that would allow them to at least survive and why not, do even more...

Technology itself (e.g. cheap, abundant, clean energy - cheap 3D printers capable of reproducing almost anything - etc.) might (and hopefully will) solve many of the upcoming problems.

Also, with all this advancement of computers and robots, let's hope Skynet doesn't become self-aware. But if it does, let's hope it likes us.

I feel that I used to achieve a far deeper level of thinking before the advent of the internet.
