What if, because of his lack of memory, Alastor is all for exploring the technology that advanced after his death?
He'll still insist it peaked with his time, but he does like watching radio repair vids and cooking channels.
This is a whole new level of complicated for Vox.
I'm actually planning to do something like this! The time period when Alastor was alive was actually a time of technological innovation, so I headcanon that his problem with new technology isn't that it's new, but what capitalism has shaped it into; user-unfriendly, hostile design, planned obsolescence, cheaper, less durable parts. And his whole thing with Vox only turned his disdain for it up tenfold.
Without his memories, Side Effects Alastor is pretty curious about 'futuristic' technology. And in a way, this is one of the things that the hotel guests find endearing about him. Because he's curious and open to listening and lets them guide him. And really pretty.
He turns that around on Vox though, playing innocent and curious so that Vox can feel like the big, smart, in-charge man and show off all of his modern tech to Alastor, only for Alastor to then use this knowledge to sabotage it.
