A quick search gave me the information that death by suicide is going down. If there is an increase in anxiety and depression, I see no reason to blame social media. If used in a good way, social media make us feel well.
Anxiety, depression and suicides are nothing new. I don't blame on either ordinary or online social interaction. Instead I think social interaction is healthy, given it has a good quality, whether it's online or not.
I don't think they are paid for having money. When saving money in a bank, you don't have the money. The bank has it, and you are being paid for letting them have your money.
I don't think noise is necessary. It's only that people are used to noise. I usually wear sound isolating earphones outdors, so I don't hear cars as much now. But to compensate for that I look more around. That's something everyone could learn. Exception is those that are blind, but I think they should be able to get some help from technology to warn them from cars.
It's a waste to not give the best software possible to the car. In a car, a higher price is only natural if the car is more expensive to produce or develop.
