So many startups with such low sample size pitch big on AI/ML/NLP and every things else under the sun. AMZN and other bigs not able to win it, says loud that it is complex, and very algorithm can always be introduced to weight a bias. AI telling me it is time to eat/drink/workout is very different from AI evaluating my social media feeds and recommending topic/time to post, to get me more reactions. Whether what I share has value or not. AI/NLP to transform mundane tasks into automation is always a goal to achieve :)
