There is already slow migration of jobs to care homes, it does feel like we are experiencing that change of jobs required to keep capitalism in place. I would really like to see us go the way of the four-hour day, it an idea that is slowly gaining traction, although there are also things like universal basic income that could also offer viable alternatives. I can't wholeheartedly believe that anyone who currently holds all the top of the pyramid power would to take the steps necessary to help create any of them. I hope I am wrong.

The subtle, and therefore accepted, rise of the sinister is always a concern, but as long as it is, and we have scifi and speculative fiction like black mirror, then hopefully it shouldn't get too far unchecked.

The block chain could eventually be used as a primary historical source, free from rewrites and redaction's, although there's still no accounting for bias, it would at least give everyone who could access it views from all sides, instead of the tinted history we get now. Although equally the fact that once information on, it can't be removed, and can be accessed by anyone, does have equally less savoury applications. For every possible way I can think of for it be an asset to our species, it works the other way.
