About ten years ago a research team concluded that electrons last for at least 10^28 years. Which is just a lower bound, and did not establish an upper. Rereading it now, it does seem that proving they decay is an attempt at a new branch of physics. So they might decay or they might not.

Can you link that paper? Or name at least one of the authors? Not to mention that checking for a lower bound means nothing for a potential upper bound.

It's ridiculous to cite an unnamed paper while being unable to procure a single source on the internet and then proclaim it's equally likely that they might or might not decay. With everything we know about physics there is absolutely no way imaginable that they might decay.
