This is true in many ways. There is always someone looking to take advantage or misuse tech. It can't be avoided and will probably never go away. I try to take the good with the bad personally. With cars we get car crashes and with planes we get plane crashes. The problem is that living in fear of advancement does nothing but holds us back. We couldn't possibly be were we are as a species if we lived in fear of moving forward.
Then again, some of the dark sides you refer to are hyped by those wishing to sell us protection. Take identity theft as an example. People are generally terrified of it. They spend a ton of money to help prevent it. Many avoid doing certain things online because they are so concerned about it. Problem is that majority of identity theft comes from people going through your garbage and not finding your info online. Most criminals are pretty low tech because most of them really aren't that bright, which is why most of them are criminals in the first place.
See, I'm one of those people that doesn't leave the room without my phone.
As far as the gym equipment goes, there are apps that help you track your workouts. They can help you look back at what you've done or what has been most successful for you. I wasn't too into working out at first, but after a I while I started to love it. It has become very necessary since I don't eat right and I quit smoking. Going to the gym is the difference between me being a size 6 or a size 10.
I understand where you are coming from. My girlfriend is the same way. If she had her way we would all be using pen and paper. The only thing she likes about any tech is her laptop even though she is convinced that it hates her.
