I have a manager who does the "teaching" thing poorly. If you're making a request in the form of a question, fine. But if you're trying to make me THINK, fuck off.

Basically returning to Pneumatic tubes but probably way less elegant and over-engineered

What if the state is the US demanding data using NSLs or dragnet warrants?

But it will be bar policy to have your name/address/email info or their reader won’t authenticate you.

I'm perfectly happy not patronizing those establishments.

With the current system, I could easily believe that not all bars scan the barcode for a nefarious reason, but do it just to make it easier to avoid a bad manual reading (different ID layouts per state, darkness making it hard to read, etc.).

With this kind of digital ID, requesting anything more than my age and photo is an immediate flag to me that they're explicitly looking to do something shady (or at least they're incompetent and don't know how to use the reader properly). I would deny everything but the age and photo request, and if they balk, I'd ask to speak to a manager or just walk away.

Or there’s cases like WMDs or “Assad gassed his own people” which are outright frauds coming from the establishment who determines what is factual.

I don’t like the “unbanked” basis for these anti cashless arguments because they’ll just solve that problem.

No they intentionally put those sources higher in the results even when there’s more popular content below it. They get extra priority as they’re deemed “authoritative sources.” So if you’re searching something political you’ll get a Washington Consensus result every time pretty literally. If you search names of recent mideast wars, CFR appears to be a preprogrammed result like Wikipedia.

You don't necessarily know that source for CFR is necessarily less popular than Wikipedia: plus CFR is not necessarily Washington consensus. In addition to that it's much better to have informed discussion on a topic rather than some misleading news source.

google also has a definite opinion on news, politics and other controversial topics which will get worse and worse during election years or during times of war.
