Can we not do better than "nasty, brutish and short"?

Reading about sexism in the tech industry, and helping my daughter deal with bulling at school, I find myself yet again despairing of human nature. Is human life inevitably "nasty, brutish and short"? What makes us so blinkered to the consequences of our actions, so disconnected in our thinking?

The internet and social media are often blamed for our failings but they are just a mirror. They don't make us anything - they show us what we are. I remain hopeful that they are one of our few hopes of improving.

We are having our uglier behaviours held up to us for inspection. This feels uncomfortable and the first instinct is to hide them again. But we have to work through the discomfort and work things out.
