Most frightening and/or depressing story:

• Pilots occasionally go crazy and crash planes on purpose.

Most hopeful story:

• Deep inside me is a little boy who still likes bugs, and I spotted some cool bugs in my 2019 garden, including endangered Monarch butterflies. So at least I made that small difference for biodiversity in a small urban garden, and others can do the same.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both:

• Estonia is supposedly the most digitally advanced country in the world. Finland has posted a free AI literacy course.
