This is interesting, I worked directly with homeless people for years, and remember how frustrating this dynamic was. There was always this ask we made of the homeless, especially since at the time I was in a religious outreach role and had to follow my direction & training. But after a while it seemed only rational to expect that the ask is not going to work out or lead to anything but heightened anxiety on the part of all parties. So here, have some fresh trauma with your trauma!
IMO this is a place where I could see AI-style boilerplate-frameworking helping in the right set of circumstances, if such tooling could help remove some of the human tension from the situation. But overall what is needed IMO is a flexibility of accommodations that we haven't seen before, and which has never been institutionally available before.
Eventually in my mind there will probably be a radically different conception of availability and tolerance for a variety of living situations/environments/accommodations, and this will eventually displace even the concept of mental illness as it is known today, to say nothing of homelessness.
Some other big changes IMO will also be relational, as various changes of this sort help people understand just how much our personal expectations (based on our own past experiences) weighed on others and tilted past outcomes in a way that blinded us to creative and effective interventions.
I also thought that the "disgraceful" quote at the end of the video, referring to the entire situation, rang pretty hollow. This is also a cultural learning process and we've never faced this set of circumstances before at such a level from a variety of viewpoints, even looking back to homeless & refugee crises of the past.
