With all the money that you save you can experiment with humans close to Earth and use the money you save to send many robots to do the actual exploration, which will survive longer than humans and do much more work.
Of course you won't get the same publicity. So maybe just for that it's better to send humans, but not for scientific reasons.
" [...] to obfuscate browsing data and protect users from surveillance and tracking by advertising networks."
So while it may be a negative side effect the point of the extension is not disrupting online advertisement, but disrupting online tracking. Even though you will be effectively doing both.
Even leaving neurochemical pathways aside, our culture is like that in many aspects. I mean even selflessness is the way many people understand being a good person, doing something good that feels bad is supposed to be better than doing something good that also feels good. I don't agree with that view, but it's pretty much ingrained with out western culture.
I think the problem and criticism is that many of those programs aren't programs at all, and they aren't based on anything, not even personal experience. If you look at any elite crossfitter his training is more likely to look like traditional strength training with proper form lifting, plus maybe WOD for the conditioning part, than pure crossfit WOD centered training. Centering the training in whatever weaknesses he may have, and so on. And of course whatever exercise they are planning to compete on.
Of course if your trainer is a good trainer you are going to get that, in a normal gym or in a crossfit gym. The problem is that as a program the base crossfit program doesn't offer much to a novice, except for the community and the encouragement that comes with it to pursue high intensity training. But outside of that the program itself won't offer any proper guiding unless you have a trainer that provides that guiding outside the program.
Syriza in Greece won the European elections and may govern in the future. FN is rising in France. UKIP in UK.
And in Spain Podemos is not fizzling out at all, the last polls put it as the 3rd party and getting very close to be the 2nd one, and even if they disappear what the polls seem very sure about is that neither center-right nor center-left could govern by themselves, and if they need to create a coalition that would mean political suicide for any future elections, at least with the current political atmosphere, maybe they are able to sell that coalition somehow. But there's probably too much corruption at the moment to sell it as anything else than as the last "let's keep stealing money" card.
