Grateful to The HealthTech Signal for placing me at #2 on its list of 100 health tech influencers. There are many worse fates than trailing @EricTopol, and the list includes many of the folks I follow for health tech/AI insights. https://t.co/m4EUNckpsH https://t.co/8YsxgfkO6c 11.7K views · 103 likes · 7 reposts · 7 replies 01 Sep 2026 In @WIRED, @StevenLevy dives into the "Will we need MDs?" debate, fueled by the recent @ZekeEmanuel @VinodKhosla @nealkhosla & @AbeBakerButler @JAMA_current article.
