Just imagine what others can do on other planets that are millions of years ahead of us. That is what people should consider.

True, but if the laws of physics absolutely prevent FTL travel, then a million, billion or trillion years more advanced makes no difference. There would have to be ways to travel FTL or a way around it to make interstellar travel practical.
