If you know you will be memory-wiped after an hour, it does not make sense to make long-term plans. For example, you can read a book you enjoy, if you value the feeling. But if you read a scientific book, I think the pleasure from learning would be somewhat spoiled by knowing that you are going to forget this all soon. The learning would mostly become a lost purpose, unless you can use the learned knowledge within the hour.
Knowing that you are unlikely to be alive after 100 years prevents you from making some plans which would be meaningful in a parallel universe where you are likely to live 1000 years. Some of those plans are good according to the values you have now, but are outside of your reach. Thus future death does not make life completely meaningless, but it ruins some value even now.
I do agree that there are things you might think you want that don’t really make sense given that in a few hundred years you’re likely to be long dead and your influence on the world is likely to be lost in the noise.
But that’s a long way from saying—as bokov seems to be—that this invalidates “everything on which we base our long-term plans”.
I wouldn’t spend the next hour reading a scientific book if I knew that at the end my brain would be reset to its prior state. But I will happily spend time reading a scientific book if, e.g., it will make my life more interesting for the next few years, or lead to higher income which I can use to retire earlier, buy nicer things, or give to charity, even if all those benefits take place only over (say) the next 20 years.
Perhaps I’m unusual, or perhaps I’m fooling myself, but it doesn’t seem to me as if my long-term plans, or anyone else’s, are predicated on living for ever or having influence that lasts for hundreds of years.
