“With bitcoin, we have one large, interconnected computer network which controls many, many human counterparts.
More importantly, it controls one of the most precious aspects of our lives – financial livelihood. An exact reversal of how the computing revolution began is characterized by an inflection point of control which has just recently passed.” – URL
The notion of “control” implies a will, or a motivation. As machines won’t have that, or feelings, for a long time to come, the Bitcoin network will more be about providing the most crucial part in the information chain online; the “true” state of things (especially value, but also info on what has happened), i.e. no, the Blockchain does not control us, it helps us.
