Just watched two founders on a panel, both who sell services to the NHS, both just answered a question about how to sell into the NHS by saying that it's too hard, and they shouldn't try. "Choose another vertical", one said. This makes me sad. If worked in the NHS it would be make me very sad.

Juries are not perfect. Many of the worst miscarriages of justice have followed jury trials. But the merit of juries is not so much the power they have, but the power they prevent others from having. They mean a judge cannot just nod-along with prosecution evidence and give a guilty verdict.

According to Yougov, 69% of people support the Online Safety Act's age verification, but only 24% of people think it'll actually work. Meaning a considerable group of people support it even though they don't think it will work. Which is a bit depressing, isn't it? yougov.co.uk/technology/a...
