Interesting, thanks for sharing.
This letter touched on something I've been thinking about a lot recently, which is that while many of the tech start-up services that fall under the category of "Things my mom no longer does for me" have been marketed at Millennials, they will have truly amazing benefits for aging Boomers. I love the fact that as my parents age and stop being able to drive Uber and Lyft can take them just about anywhere, preserving their mobility. My grandma relied on the bus (in a city with poor bus coverage), a senior citizen center shuttle, and her children to get around. It's easy to have dinner, groceries, basically anything, delivered. With services like taskrabit you can get someone to come lift something heavy for you, or put up that painting, or whatever. They can have any kind of entertainment they want beamed into their home, without relying on anyone else.
These are all the things my parents did for their parents as they aged, and I saw the stressful dynamic that sudden dependence caused, on both sides. While I'm happy to help my parents in anyway they need, I think they'll be happier retaining a sense of independence as they grow old, and will feel like they are less of a burden on their children. Note the important caveat that my parents can afford retirement, which I am thankful every day for, because these services will cost money.
