What coming technological advancement do you expect to have the biggest impact on your business?

As a therapist for professional money managers and entrepreneurs, my goal is to invite my clients to expand their rapport with all parts of themselves and the world they live in. One of the biggest entries to their internal landscape is their physiology. I watch every tick on their face, their breathing, and posture. By expanding these clues, we clarify the various conflicts that keep them from their goals. With more online work, this becomes more challenging. What if my clients had sensors that charted their physiology in real-time while we talked? I could see immediately when we hit a subconscious hot spot.
