It’s a question of overpromising and underdelivering. I’m not anti science. The scientists should definitely go forth and science. It’s the marketing they are bad at. The boy who cried wolf is not a training manual.
Scientists have to get good at marketing because they will not get funding otherwise. They have to pitch their research towards an interested panel though, whose members have background knowledge. This means that they can merely bend the truth and exaggerate the potential impact of their research.
Popular science magazines are quite different. They publicize for views, and nobody cares how accurate they are.
Presentations of a public company are somewhere in between. The target audience is not nearly as qualified as a scientific grant panel, but they can sell shares or even sue the company if it underdelivers on its promises.
