High-trust and low-trust understate the severity of the phase change, which is more accurately described as a shift from trust-density to trust-sparsity. You go from a state where people spawn with the "bozo bit" off to one where they spawn with it on. You get a completely different political dynamic when that happens.
Obviously, trust has varying degrees and context. In Japan, you can leave your laptop at a cafe; in the U.S., you probably wouldn't. That doesn't mean that we're "low trust" or trust-sparse. We might generally trust most people to be decent while aware of the ~0.05% (?) chance per person (that someone steals the computer.
What is changing is trust with regard to competence. People were never so foolish as to trust all others without limits, but there used to be an assumption of competence in the professional world. Institutions like universities are less trusted, and so are people in general when it comes to basic competence and readiness for autonomy. It would be unthinkable, 20 years ago, that CS graduates from MIT and Stanford could be expected to justify hours of their time in "Scrum ceremonies" (which means that they aren't trusted, which means that their credentialing institutions and work experiences aren't trusted). Even average programmers in the bowels of Fortune 500's IT organizations had more autonomy than the typical "Agile" programmer today.
Right now we are in an era of organizational decline. It's not necessarily catastrophic; it might not even be bad. What it does mean is that institutions (universities, professional organizations, corporations, and even unions) have lost their role as central brokers of trust. It raises interesting questions. Thus far, most of the successful startups have been beneficiaries of institutional decline (and, again, some of those institutions deserved to break down, so I'm not moralizing) and there doesn't seem to be any economic reward to build institutions (as opposed to mere corporations, smaller in scope) up... so it doesn't happen.
