I'm not a luddite. I love digital technology and lots of other things that are new. I make my living as an IT person.
But there are some worlds where I don't want digital electronics. My preference is to keep it out of my musical life. I'm a semi-professional singer. I rehearse three hours a week and perform a few times a year. I use sheet music on paper, and I use the kind of pencil that needs sharpening. I have not learned any scoring software, and I have not digitized any of my music. When I'm making music, I use a different part of my brain, and that part was developed before I ever saw a computer. It gives me a rest in a way. I like being a pencil and paper guy three hours a week.
I tried my sister in law's bike with Di2. It works great. I own lots of bikes, and all of them are old. I'm not close to buying a new bike. If I were to buy a new bike, and if it were to come with electronic shifting, and if it doesn't add unreasonable cost, I wouldn't mind. But right now, it's very expensive and not worth it for me.
I understand the preference that @
Kapusta and others have, wanting to keep digital stuff out of the bike realm.
