I work in the semiconductor industry. Moore's Law makes it a 24/7 operation. It's rare that I need to respond quickly, but when I do, it could mean saving literally hundreds of thousands of dollars of lost production an hour. When I go on vacation, I make sure everyone knows who my backup is. And I have no idea who could be calling or texting me, and most of the time when I'm contacted by my co-workers, it's not an emergency - we don't have a special "bat phone" to use.

I have a "glass half full" way of looking at it. My "tether" frees me to move about the country. I can leave my place of work to do personal things, like dropping off a frame at the powder coater, or maybe going on an afternoon ride and still stay in contact. It's not a business for those that can't easily compartmentalize work.

That said, my wife tends to text me sometime on my ride home when she thinks of something to pick up at the store. And you don't "manage" a wife - at least not mine. She doesn't mention it very often, but she does worry when I'm riding home in the dark, or in the rain, or recently, in the snow. Being able to reply quickly gives her peace of mind.

Technology can work for or against you. I choose to use it in my favor. One of the main selling points for smart watches, it would seem, are the fitness apps. I have little interest in using those. I don't track my cycling mileage, but it is good to know how many miles I have to go to finish a ride to plan for stops, eating, etc.

YMMV
