3 - Dual SIM capability
iPhones now come with eSIM (branded as Apple SIM), which alleviates a lot of the need for this: you can have an arbitrary number of software-defined SIMs installed and switch between them at will.
What are you talking about? It's not middle management's decision about where to base their company and operations; that comes straight from senior management.
It's generally middle management's decision whether to hire people who will work remotely, whether to hire full-time employees or consultants, and so on.
How so? If you're an on-site consultant, you have to pay the living costs in that area, unless you're living in your car or something. If you're talking about being a remote consultant, then sure that works out great but how many people are able to get a gig like that?
I found no shortage of companies willing to have me work remotely, even back when I was starting out and had little reputation. I almost never worked for someone closer than 3 time zones and often for people 6+ time zones away (in both directions). I was cheaper than anyone living in SV, about the same price as people in the mid-west, and a lot more expensive than people in Russia, India, and China (I had a few contracts doing design work that would then be implemented by cheaper teams because of this).
Concussion covers a multitude of injuries. I've had a few, the worst when I was a child and decided to swing from some scaffolding that turned out to be less stable than I thought. I fell backwards and hit the back of my head on the corner of a doorstep (the concrete - the softer wooden step hadn't been installed yet). I spent the night in hospital, but was fine the following day. In the more mild instances, I've had a brief response check at the time and otherwise continued (though with a splitting headache).
A concussion just means that your head has been hit hard enough that your brain bounces off your skull. That can be fatal, or can be something that you shake off immediately, depending on the amount of force and the angle (and, presumably, how bouncy your brain is).
As long as populations increase and jobs are available the demand will continue to push prices up.
That's two conditions that could cause a pop. Number one: companies realise that there's a big advertising bubble and little ROI from online advertising. Companies like Google, Facebook, and so on that depend heavily on advertising revenue see a massive drop in customers and have to aggressively start trimming workforce. Sudden drop in bay area jobs and people have to pack up and move to somewhere where they can get a job and afford to live.
Number two: cost of living reaches a point where it's cheaper to open a new office somewhere cheaper than to expand you SV presence. Jobs don't leave the area, but new jobs appear elsewhere instead. Gradually the exciting tech developments move so that management also moves to the other areas and eventually the SV office becomes the satellite office where people who retire or leave aren't replaced.
Justice is also about sending a message

Yet magic and hierarchy arise from the same source, and this source has a null pointer.
