The scary thing about all this is that a few people read an article or two and then they decide that they won't give their children vaccines at all. There have been ineffective vaccines. There have been bad vaccines. There are some possible side-effects from vaccines, but the overall positive effect of vaccines far outweighs any negative things that could happen. All vaccines that are administered to the public go through extensive testing. But not getting vaccines, you can put not only yourself at risk, but also other people. If you don't vaccinate your daughter against rubella, for example, then she later get pregnant and gets rubella, she will have a much higher risk of miscarriage.

I do think that it's very possible that there is intelligent life on other planets. If you disregard creationism, then it's completely scientifically possible that life could come to be on another planet, just as it did on earth. It seems like there's just about an infinite amount of galaxies and stars with their own planets. That makes it pretty likely that there's something alive out there. I don't really think that there have been aliens on earth or that somebody is trying to hide them from us, but who knows. The next question is, if there are intelligent beings out there somewhere, do they look like us?

I definitely agree than automation will play a massive role. Machines and computers are replacing so many jobs. Even if you just consider drivers. What percentage of jobs in any given company are just driving? There are truck drivers, taxi drivers, bus drivers, food delivery drivers, couriers... I'm sure there will just be more and more self-driving cars in the future. All those drivers will be out of a job. You can go on and on about jobs that are being replaced by technology. Some call center jobs are even being replaced by automated systems that are actually starting to get pretty good. It's funny sometimes to see governments scramble to "create jobs". That's not going to be the solution. It has to be something bigger than that. I like that some countries are already experimenting with the idea of a universal income.
