Reasons for optimism after a difficult year

Bill Gates recently posted his highly informative Year in Review: Reasons for optimism after a difficult year. He is such an inspiring writer, and this piece is a great summary of the challenges and triumphs of the last year including messages like:

• Why I’m hopeful the end of the COVID-19 pandemic is finally in sight.

• This (COP26) conference made it clear that the world is engaged and making progress. We still have a lot more work to do.
• My work has always been driven by a simple idea: The world can get better.
