The generation they belong to are predicted to live to what 80-85 years? Whilst we (assuming you're in your 40's now) are predicted to get to what 90-95 on average?
Average lifespans are increasing, and on top of that the mobility of someone who's 75 now, won't be the same of someone who's 75 in another 35+ years.
That may be true, but will we (who are in our 40's now) have the same quality of life at 90-95 as a now 75-year old will have at 80-85?
Who do you think would "allow" this? God? This is a resource constraint imposed by reality itself catching up to an excessively idealistic set of policies; this policy decision is downstream of that, not arbitrary.
Looking at older people around me, most lead a much less active life after 75. So, if we were lucky we used to have some 10 good years of doing whatever we wanted before old age and age-related diseases start affecting us so much we become limited to a much smaller world. But now we have maybe eight years and if we follow Denmark, five years.
I think if you've put in 40-45 years for the man, you should be allowed to have some good 10 years for yourself. Travel, play golf, cross a continent in a camper or climb a mountain.
Why would the sharding hash computation be expensive? MD5 would be suitable here; it's blazing fast even when used for 10s of thousands of operations per second on large keys.. it will work fine.
I wish the author had given firmer details on why they abandoned approaches that are proven to work across a wide variety of use-cases.
Perhaps, or perhaps we don't know what the fall of civilization looks like? I remember watching a talk by Jonathan Blow where he poses that question. Did the Egyptians who built the pyramids realize when their civilization fell or did it just look like business as usual until it suddenly didn't?

If you work in a team in any capacity then you need to have a strong baseline of trust in order to work effectively.
Trust is the building block that all effective team performance stacks on top of (see 5 dysfunctions of a team).
You don't just get trust for free, you have to build it by creating moments like this where people can demonstrate vulnerability around each other.
