AI is the most profound technology I’ve seen, both in its ability to help people and to disrupt their lives. I’m optimistic about the good it can do, but we need to take its risks seriously. b-gat.es/4zLk2T3

Aviation is one of the hardest parts of the economy to decarbonize.

I appreciated the opportunity to speak with @ezraklein at length about the state of AI. I believe the world isn't awake to the dangers of this technology and the choices humanity has to make. AI will either be the greatest tool for opportunity and equality we've ever seen—or the…Mostrar mais

We need to put the appropriate AI safeguards and monitoring in place now—to both prevent a loss of control and stop bad actors from using the tech to cause harm. If we minimize the risks, we’ll get to benefit from AI’s immense potential in fields like medicine, education, and agr…Mostrar mais

I’m deeply sad to learn of the passing of Dr. Bill Foege. Bill was a towering figure in global health—a man who saved the lives of literally hundreds of millions of people. He was also a friend and mentor who gave me a deep grounding in the history of global health and inspired m…Mostrar mais

Learning how many kids were dying from diarrhea back in 1997—when I never worried about it with my own kids—led me to get involved in global health. gatesnot.es/46lTfBz

The facts are simple and devastating: Aid cuts have already cost lives, and the number of deaths will continue to rise. Here’s the evidence.

I had a great discussion with @narendramodi about India’s development, the path to Viksit Bharat @ 2047, and exciting advancements in health, agriculture, AI, and other sectors that are creating impact today. It's impressive to see how innovation in India is driving progress loca…Mostrar mais

Congratulations to @narendramodi on winning a third term as Prime Minister. You have strengthened India's position as a source of innovation for global progress in sectors like health, agriculture, women-led development, and digital transformation. Look forward to a continued par…Mostrar mais

A few highlights from another incredible trip to India: gatesnot.es/3vbmkzd

It is always inspiring to meet with @narendramodi and there was a lot to discuss. We talked about AI for public good; DPI; women-led development; innovation in agriculture, health, and climate adaptation; and how we can take lessons from India to the world. @PMOIndia

Some memories stick with you forever. Others follow you around the internet for 28 years. Happy birthday, @Windows.

Really good news: Renewables now account for about one third of electricity generation globally, and the share is increasing. b-gat.es/3On0O1F

I’m in Kenya this week to learn from researchers, innovators, students, and leaders about what’s working, what’s not, and how the foundation can better support progress in Kenya and across the continent. b-gat.es/3UGjbiH

Life is more fun when you have a friend like Warren. Happy 92nd birthday!

I’m at my happiest when I’m learning – no matter how gross the subject matter. Today, I experienced the Meguro Parasitological Museum in Tokyo, and saw what is believed to be the world’s longest tapeworm. 10/10 would visit again.

As India celebrates its 75th Independence Day, I congratulate @narendramodi for prioritizing healthcare and digital transformation while spearheading India’s development. India's progress in these sectors is inspiring and we are fortunate to partner in this journey #AmritMahotsav

Congratulations @narendramodi for yet another milestone of administering #200crorevaccinations. We are grateful for our continued partnership with Indian vaccine manufacturers and the Indian government for mitigating the impact of COVID19. www.hindustantimes.com/india-news/india-cr...Mostrar mais

Thank you @ImranKhanPTI for the productive discussions on the steps being taken in Pakistan to eliminate polio. I’m encouraged by the country’s commitment to eradication and am optimistic that if everyone remains vigilant, we can #endpolio.

India has administered 1 billion vaccine doses, a testament to India’s innovation, ability to manufacture at scale, and the efforts of millions of health workers backed by CoWIN. Congratulations @narendramodi @mansukhmandviya @PMOIndia @MoHFW_India b-gat.es/30Uboa1

Congratulations @narendramodi on the national launch of Ayushman Bharat Digital Mission. This digital health infrastructure will help ensure equitable, accessible healthcare delivery and accelerate progress on India’s health goals. @PMOIndia @MoHFW_INDIA b-gat.es/3ifL67O

One of the benefits of being 65 is that I’m eligible for the COVID-19 vaccine. I got my first dose this week, and I feel great. Thank you to all of the scientists, trial participants, regulators, and frontline healthcare workers who got us to this point.

I look forward to working with President @JoeBiden and Vice President @KamalaHarris to tackle some of our toughest challenges like COVID-19 and climate change. This has been a troubling time in America, but I see promise in the months and years ahead.

It’s great to see India’s leadership in scientific innovation and vaccine manufacturing capability as the world works to end the COVID-19 pandemic @PMOIndia b-gat.es/3hFKNBL

I look forward to working with the new administration and leaders on both sides in Congress on getting the surging pandemic under control, engaging partners around the world on issues like poverty and climate change, and addressing issues of inequality and opportunity at home.

Congratulations to President-Elect Biden and Vice President-Elect Harris. Thank you to the election officials and campaign workers who worked tirelessly to ensure a record number of Americans could cast a ballot and have it counted during such an challenging time for our country.

Of all the things I’ve learned from Warren Buffett (and there have been a lot), the most important might be what friendship is all about. Here’s why he’s a person that I admire as well as like: gatesnot.es/34KvYcv

I am committed to listening and learning more about systemic racism and what I can do with my actions and words to help create a more equal and just future. Black lives matter.

The horrifying killings of George Floyd, Ahmaud Arbery, Breonna Taylor and far too many other Black people—and the protests they sparked—are shining a light on the brutal injustices that Black people experience every day…

Most of my conversations these days are about COVID-19 and how we can stem the tide, but I’m also often asked about what I am reading and watching. Here are my 2020 summer book recommendations (plus a few other ideas for things to do at home). gatesnot.es/3bI6FaT

There are over 100 different coronavirus vaccine candidates in the works. These candidates take a variety of approaches to protecting the body against COVID-19: gatesnot.es/3aYXP8d

Humankind has never had a more urgent task than creating broad immunity for coronavirus. It’s going to require a global cooperative effort like the world has never seen. But I know we’ll get it done. There’s simply no alternative. gatesnot.es/3d06cC2

We don't yet have all the tools we need to stop the novel coronavirus and safely re-open the economy. But they are on the horizon. gatesnot.es/2S2v7g9

Halting funding for the World Health Organization during a world health crisis is as dangerous as it sounds. Their work is slowing the spread of COVID-19 and if that work is stopped no other organization can replace them. The world needs @WHO now more than ever.

On #WorldHealthDay — and every day — I want to thank all of the health heroes for their sacrifices and for keeping us safe.

There’s no question the United States missed the opportunity to get ahead of the novel #coronavirus. But the window for making important decisions hasn’t closed. The choices we and our leaders make now will have an enormous impact. wapo.st/2R4BKho

One of the questions I am most often asked about the #COVID19 pandemic is how, and when, it will end. This article by @edyong209 does a really good job of outlining the steps we need to take. b-gat.es/2QU3Njx

I’ve been impressed by governors across the country including @JayInslee, @NYGovCuomo, @GavinNewsom, @GovMikeDeWine, @GovLarryHogan, and the many others who are guiding their communities through this challenge and providing a model for us all to follow.

Back in my early Microsoft days, I routinely pulled all-nighters when we had to deliver a piece of software. I even stayed up two nights in a row on occasion–I don’t recommend that. This book taught me a lot about the importance of a better night's sleep. gatesnot.es/34naYVBMostrar mais
