I suspect that they meant a source that indicates that this is a path of research that is currently being pursued and likely not due to skepticism, but rather interest. I can understand, because I didn’t know it was something that people were actually researching; I mean, I first heard of the idea in a sci-fi novel!
Personally, I like to try to give people the benefit of the doubt, so I’m going to assume that maybe you were/are just having a bad day and didn’t mean to be rude. I hope that the rest of your day was/is better!
