All modern appliances and HVACs are using inverter drive motors for efficiency. Brushless DC motors are more efficient though.

Depends how you define dangerous. If we look injury rates and not deaths, meat processing/packing is the most dangerous.

Not even the most dangerous job in the US. Forest workers, commercial fishermen, pilots etc are more dangerous. If we're talking about gun violence, your corner market cashier is more likely to get shot, Has anyone thanked a 7 eleven worker for their sacrifice thas you can get a slurpee at 2am?

If I have a free app that hits location services on the device and I sell this data, how does Apple and Google make money from me?

It's a chance for $400m. Doesn't mean he can get the $400m, since legally it still isnt his and it still can get seized after he gets out if he ever tries to cash it in,

Priced right if money is moving from the bottom 90% to the top 10%. Stock market growth is because theres excess money and people need to invest the money. Supply and demand. There's reason why you can buy any ultra luxury car right(look at ferrari's revenue growth) and private jet industry is booming.

OS kernel runqueue is using a spinlock to schedule everything. So it works. Should you ever use a spinlock in application code? No. Let the OS via the synchronization primitives in whatever language your app is in.
