Yeah, this is why I don't think we'll ever achieve this and I very much doubt other species have or will either. I don't think the incentives are there to expend this kind of energy (and capital) trying to get to another galaxy - especially since it would a very, very long time before anyone would know if the project succeeded (if it would ever be known at all)- there's no success feedback for a project like that. Interstellar travel will be difficult enough and the feedback time there would likely be at least a couple generations (longer depending on where the travel is to).
