THE IRISHMAN(2019) uses deep fake for de-aging the actors. As the main actors are all old in real life, the CGI team generated deep fake videos of the actors by using the data from their old movies when they were younger.
That does sound like a problem, but unfortunately since we cannot do much about tree physiology(they need to shed their leaves to survive winter) and gravity (leaves should fall down); I think the cost-effective way to address this problem is to buy a leaf blower and asking someone else to clear the leaves every day by creating a small fund for it by the residents themselves.
The solution which addresses this need gap can also solve other problems such as identifying involuntary pornography by the victims or law enforcement to initiate takedowns. But, unfortunately in-spite of excellent improvement to computation and image processing; due to the massive size of the data (number of videos) hosted in popular platforms this kind of solution is limited to implementation by the respective platform owners(it is even hard for them to implement).
I think the task-management tools should form a consortium and lobby governments to pass regulations to protect one's time from being encroached by the corporations for the task-management apps to do their thing.
Olive Smart Ear (https://www.olive.store/en/product/) solves this problem, it received good feedback in the CES 2020. I'm sure more TWS earphones manufactures would enable hearing aid features this year fulfilling this need gap.
