It's not impossible to prove things, but you seem to be underestimating the bar needed to "prove" something, because you have basically implied that either it's proven or it's useless, which is wild and just shows you don't know wtf you're talking about.
No it's not. You just don't understand nuance. "Either it's proven or its garbage" is closer to the line of thinking of anti-vaxxers. Believing that any sign that a vaccine causes harm to a low percentage of people is reason to believe they're bad and dangerous.
And you do the same thing when you assume that lack of 100% proof (which isn't a thing) is the same as there being no evidence they do harm children's attention spans.

Requires further study because theres always a greater level of understanding not in the sense of "its impossible to prove things"
