When traveling, a funny thought I always have is watching other tourists take the same photos, from the same exact ___location, knowing it will be backed up to iCloud. I can't help but imagine how much disk space is taken up by duplicates of the exact same photo.
For a fun example, every time I'm on the Las Vegas strip I see dozens of people taking videos of the Bellagio Water Show.
There are 30 shows per night, if 50 people take videos in 4K 60fps (default on new iPhones), that's around 60 GB of data per show or ~600 TB per year of just videos of the Bellagio Fountain Show!
I am not sure if this the same, but this reminds me of the Abilities system on the Move language[0]. It allows you to create linear, affine or other type constraints in a pretty flexible way.
Almost had to get neck surgery from a BJJ injury + sitting on a computer all day. This was after BJJ training 3 times a week + lifting twice a week. Would wake up with numb pinkies and would experience shooting pains up and down my neck as I was sitting at my computer.
The thing that prevented a surgery for me was simply fixing my posture, by strengthening the upper back and neck muscles. The most effective exercise I've experienced to achieve this is cable face pulls, with a grip that externally rotates the shoulder. You can see an example here[0].
Non-gym related thing that also helps with posture is getting a standing desk. Its not even necessary to stand, but simply having the ability to change the height of your desk is a massive help for getting the correct sitting posture.
Setting aside personal opinions, I think the protocol is useful but should be able to encompass any payment system/blockchain thru a completely neutral and agnostic interface.
