> Today's tech companies can influence voters in subtle ways and run huge PR campaigns to influence voters. In the future, only favourable legislators will come into power and laws ...
But favorable to which corporate interest or outside agency (Russian hackers)?
The corporate interests won't align on every issue or candidate, so they won't be influencing votes all the same. What's good for Google won't always be what's good for Amazon, or the Chinese government.
It's the various competing interests that somewhat cancel out. And it's not like other interests with power and money aren't aware of the reach of tech companies, and won't seek to use that to their advantage. Consider how traditional media has been used.
Or do you think the news organizations and tv/radio stations had all the power before?
Trump being elected wasn't the will of any of the tech giants. It's more of a platform that's used for whatever interest has the means to abuse it, such as pushing fake news.
