For those perplexed by the headline, the Muybridge camera moment refers to Eadweard Muybridge who managed via camera photos taken in rapid succession to prove that when a horse runs it at times has all four legs above the ground.
(On an irrelevant note, the Stanford Barn, where those pictures were taken, has gradually been closed off to the world. It was open to the public until COVID. It's still there, and there's a Stanford equestrian team, but road access has been cut and all mentions of the barn removed from directional signs.)
There are so many of these places I've encountered what used to be publicly available pre-COVID and are no longer. The reasons/excuses vary.
Example: Sometimes it's a symptom of a small business already wanted a reason to pivot to a new venture, and they keep the old thing going to profit from some old whales while in transition.
There was a lot of that post 9/11 too. It used to be that you could walk into nearly any office building in the world with little more than a smile and a confident wave. A lot of previously public areas got locked down on September 12th.
Office building security changed significantly much earlier than 2001. The mass shooting in 1993 at 101 California Street in San Francisco was the beginning of many such changes.
The attack [...] also precipitated sweeping changes in downtown San Francisco. Before Ferri walked into the building that July day, almost no high-rises in the city had security measures. While many had a front desk, only a handful checked badges. The building at 101 California had two side entrances that were completely unguarded. The Examiner reported that at the time, the Chevron building and Charles Schwab’s SF headquarters had the toughest security in town; electronic badges were required at Chevron, an anomaly in 1993.
Today, security checks are standard at offices large and small, a fundamental shift that happened because of 101 California.
I mean, honestly if this didn't happen it likely would have happened by now anyway.
Enough people would have walked in and picked up computer systems filled with company information that security would have been implemented at some point.
It's often public services that have reaffected resources while that place was closed, and found after Covid that they couldn't spare (of justify sparing) these resources again once they contemplated reopening the place.
Ie, while that historic greenhouse in the city park was nice and appreciated by some people, now that the two gardeners who were working in it part-time have to take care of the newly planted trees along the streets, it's not possible to put them back to the less essential greenhouse and they don't have budget for hiring two new gardeners. So the greenhouse stays closed.
Not only that, but the tldr basically only talks about that, so it's not much of a summary at all. I read the tldr and I have no idea what the article is about.

(the article doesn’t bother to mention any of this until near the end in the tl;dr section, which since it’s tl and you dr, you never got to).
