I personally think we'll have the opposite problem. I think making machines too much like humans will result in less ethical consideration of actual humans, not extra rights for machines.
Once a model becomes sufficiently like a human brain to perform many of the jobs we have in our society (driving vehicles, collecting trash, monitoring cameras and data streams, etc.) then those who have the ultimate power in our world will start to see humans as unimportant meat sacks that are inefficient compared to the machines. They'll stop pretending they care about the welfare of humanity even a little bit, and will start to push for policies that would reduce our numbers.
Eventually, I believe the end goal will be for a small number of humans to do those jobs that simply cannot be automated, and to serve an even smaller number of masters who control the machines, which will then be purposed as the police for the other humans.
You write in the future tense, but I think that this is already happening. Fewer millenials are having children than previous generations, and those that are have fewer children.
I think the main driver is that most millenials simply can’t afford children, and this is a direct result of policies pushed by “those who have the ultimate power”.
Or maybe the millennials themselves see humans as unefficient meat sacks who might as well just pass the time with video games rather than striving.
Or maybe people actually think every child is precious, and those who have the ultimate power benevolently used their power to require every child get the resources it deserves, even though we can't afford it.
