I had debilitating carpal tunnel typing pain twice in my life, one in college and once 10 years later. Both times was when RSI ) carpal tunnel was a very popular fad topic to discuss. Both times my interventions had no effect and the pain cleared up on its own. I never developed "good typing habits" and when smartphones came out I developed new terrible habits, but that never caused RSI / carpal tunnel pain.
