This isn't to say the criticism found there is unreasonable, just that it's not special. People in science and people in tech can get involved in politics, but most of the political issues out there are not scientific or technological so support for them will break down on ideological lines, not technocratic ones. The case of Peter Thiel isn't special, i.e. a conservative member of the tech community would not prefer Richard Stallman to Marco Rubio, just as a progressive member of the tech community would not prefer Peter Thiel to Jerry Brown.
If you want technocracy, I would suggest encouraging tech-minded folks to move to the public sector rather than run for office. Personally I would oppose that, as I think most tech talent would be somewhat wasted there.
