Studies generally take time, so if it were months later they likely had it before you. The years later is a maybe, but also possible because it takes time to get grants to do studies as well. Exceptions tend to be more urgent stuff like the pandemic, but even then we had SARS outbreaks decades ago and they've been studying it for a while, even if it wasn't specific SARS-COV-2.

Sometimes I wish just being an "idea-person" would be a paid job.

I don't want to take away from your joy and validation. You sound like a generally curious person who is frequently churning out ideas.

But that's not how ideas (for doing experiments/doing research) work. Especially not in a scientific context. You have to have intimate knowledge of any matter to sift through a huge amount of various ideas and pluck out the ones that are feasible, that make sense and that are promising. That takes time and effort. Curiosity is obviously key, but actually pursuing any idea means a lot of work. It's much more frustrating than one might think, especially because it usually doesn't work the way you initially imagine it will. And most of these ideas need many years, or even decades to develop and study.
