The entire narrative around "scientists need to learn to be better communicators" is seriously misguided.
Scientists communicate just fine. They communicate with accuracy and purpose. That is a core skill for good science and has been for a very very long time.
We need to stop blaming scientists and recognise that the media landscape is devoid of skills to understand basic science methodology and communication. And absolutely lacks the most fundamental motivations to even bother engaging with real science.
Our society is flooded with misinformation and clickbait. This is not a "science doesn't communicate well enough" problem. Media is no longer about information, it's about entertainment. The solution is not to force scientists onto TikTok. It's great when you see some scientists who happen to be effective on social media or TV... But this is not going to be true for everyone in science and neither should it be. Don't turn science communication into a popularity contest.
You're looking at the wrong end of the horse if you think the solution is just "scientists need to communicate better".
