Didn't expect India’s human development indicators to be so close to Uzbekistan and Myanmar (except democracy index. Way to give power to the people India!)

In public health, we love strategy meetings.
Someone goes, ‘Next quarter, how do we improve the health of three million patients?’
And everyone’s like: ‘We’ll build an AI solution! We’ll launch a new app! We’ll fund local partners!’

as part of a team trying to use AI to improve patient outcomes...it's really hard to hold back the urge to throw every problem at OpenAI. PHCs don't have enough meds, but sure let's make an AI chatbot to convince patients to visit the facility to collect medicines.
