The real research is useful. Putting aside nerd rapture stuff which is probably fantasy as far as we can tell it ought to be possible to make thinking machines. whether we do? who knows. Increasingly we make and use machines able to make at least some decisions and the good research into alignment and training helps with even mundane shit; such as making sure the machine is actually seeing cancers and not say the institution the MRI was taken at.
Even with relatively stupid machines it would be important to have certainty that idk a car isn't going to take a shortcut through a pedestrian. You don't need to reach AM level for it to be important that an autonomous system using some degree of heuristic decision making, quote unquote, cares about the things we do.
