What is the median age of people who are applying to Google? I suspect that many older programmers are set in their job and/or do not have the skills in the newer technology and do not apply.

TFA is beyond dumb. It's not people switching back, it's people buying a second car for their household. Many people have one EV and one ICE car.
From the summary
Overall, only 45 percent of this year's hybrid and EV trade-ins have gone toward the purchase of another alternative fuel vehicle, down from just over 60 percent in 2012.
So 65% of the time a hybrid or EV was traded in it was replaced by a conventionally fueled car. If one is buying a second car one does not trade in the first car.
It has to be used every time an allegation is made no matter how many allegations are made in one paragraph. If in any single sentence it says the suspect did something and he is found not guilty the writer could be sued for libel.
it even describes layering as something that "was" sort of an industry standard practice.
How does having a name make it an industry standard practice? "Ponzi scheme" has a name too and it is illegal. I don't see and reference to "layering" being standard practice.
is it strange to ask for a facility into hft that would cancel unprofitable trades?
He cancelled trades that would have been profitable but that he had no intention of fulfilling. He created a large volume of sell offers just above the market price knowing that no one would buy them but that it would make it appear that there was a lot of supply. That drove down the price. He then lowered his offers to keep just above. By the volume and the pattern he was manipulating the futures.
Are you an expert in how institutional high speed traders works?
Actually three Stingrays only running half the time would account for the usage.
forcing transactions on offers that are accepted
The thing is that he priced the offers just above market price so they would not be accepted. The volume of his offers made it look like there was lots of supply which made the price go down. He kept following the prices down and rarely sold anything.
The only difference here seems to be the volume of the trades.
Which crossed the line between normal practices and manipulation.
It sounds like it's a flaw in the NYSE and similar exchanges as well as greedy HFT algorithms. It seems like fixing these flaws is far more important than just arresting people who exploit them.
How do you detect such a pattern of trading?
How about you read the complaint?
Until a trial has been completed all allegations made by the government must be prefaced with "allegedly".
It has yet to be proven in court so it is "allegedly".
So was it illegal to do this?
Placing sell orders with no intention of fulfilling them is against SEC rules.
As long as you place trades on the book that you're willing to fill based on the rules of that market there's no reason why you should be called a 'crook' for that.
He didn't do that.
By allegedly placing multiple, simultaneous, large-volume sell orders at different price points—a technique known as “layering”—Sarao created the appearance of substantial supply in the market. As part of the scheme, Sarao allegedly modified these orders frequently so that they remained close to the market price, and typically canceled the orders without executing them.
He places many sell orders with no intention of filling them. While it is fine to cancel an order it becomes manipulation when one places and cancels many orders.
What's the advantage of the Stingray then?
Timing. Stingray allows real-time access to the presence of a desired number without having to wait for the information to filter through the telco's bureaucracy. A telco will not watch for a suspect while police will.
BTW, would a blanket search warrant even be Constitutional?
I bet the warrant was more like "here is the list of locations from the cell phone we would like to search". I think that because the judge approved all the locations the OP calls it a "blanket warrant".
It's time to boot, do your boot ROMs know where your disk controllers are?
