I wouldn't go so far as to call it deeply unsettling, but it does seem odd. For me, I think the reason is that I now have the desire to try and fill in all of those empty decades. And if you have only a few reoccurring tasks (go to gym), then that's all that appears year after year. That was a little odd too.
People don't do well when confronted with planning at that scale. Not only that, but when looking at decade scale, you probably don't want to see daily tasks bleeding in. It's one thing to see a five or ten year plan. It's another to see that you're still planning on going to the gym at 8:30, June 7th, 2026.
