I don't think people are angry about blockchain (the technology) but about promises people make that with this technology will solve almost any society or world problem and then attracting people to invest and then if it does not work make the promise larger and atrract more money.
To use your example: it is like Boston Dynamics and people around will start saying invest in our IRO (Initial Robot Offering) as we will solve with robots everything. We can fix with our robots democracy flaws, we can fix with our robots inflation ... and when asked how will this actually work world wide they will say "We will just build more robots, invest more money into this and then when everybody will have one then that is how we fix those problems".
See the problem here? The problem is not the robot but the company/organisation and business model trying to sell it as a solution for everything without actually talking about the solution itself nor explaining how a robot will help with our financial system at large scale. At every critique they will just say "The solution is to build more robots and thus having robots everywhere so people will think about robots and not about other stuff".
