You're right that tech isn't the solution, but it also is. A hammer is part of the toolset to solving homelessness. It can also be used to create the homeless. We can build homes or tear them down. Hell, we can even smack someone on the side of the head with one.
Tech is too abstracted, and we must concentrate on the application. There is time for abstraction and time for specification. Tech is used to extract information as well as tech is used to protect information. These are actions, not objects or attributes.
And yes, it isn't the only tool in the toolbox. But it is a tool everyone here shares in common. It is a tool that many here are using to create this problem. One that many are probably not even aware that they are contributing to. But due to the commonality of our community and the commonality in its usage to create or exacerbate the problem, it is worth mentioning and considering.
Don't pass the buck. There are no singular causes nor solutions. So if we dismiss something because it is incomplete, we will never create any solution.
Any tech we create to "solve" this issue will be worked around and/or used to cause more problems.
Tech isn't the solution.
