We live in a society with deep dependency chains on technology we can't possibly understand as individuals, that much is true

But all of those technologies are subject to independent auditing and regulation to make up for that lack of verifiability on an individual level. It is technologically feasible to apply that kind of standard to computer technologies, and in fact I would argue that it's much easier than it is for a lot of other kinds of technology we rely on. That our willingness at a political level to do so is lacking is a corruption issue, not a feasibility one.
