> something that potentially can do it better and faster will make keeping up with that knowledge all the more fascinating won't it?

Yes, but it won’t be work anymore, in the sense that you won’t get paid for it, if machines can do the knowledge work just as well or better. We aren’t there yet, of course, but this future seems quite possible and might not be that far off (possibly within our lifetime). So you could explore deep questions (that machines can explore much faster and more thoroughly) as a leisure activity, like sightseeing on vacation.
