I think getting people to read design documentation was always the challenge; this is not a new thing.

I've both produced documentation and consumed it. When I consume documentation, I don't expect much. And to be honest, I don't like the low signal to noise ratio in typical design documentation. That was always a problem. Any sufficiently complex thing is just hard into a power point friendly diagram. And anything involving boxes and arrows where the number of boxes is 5 at best, is probably not that interesting to think about.
