AI too often used for marketing only :

Fitbit sells their new tracker (coninuous HR) with added AI sleep advise (knowledge-based on massive existing sleep data, probably without continuous HR from older range of trackers).
Planning to add AI to their existing range of trackers (without continuous HR) … really, who are they trying to fool here ?
