Knowing someone with a spinal injury I can tell you that these constant innovations that won't reach the market for 20 years are kind of continuously devastating.
I've mostly given up on commenting on this on HN. I have an incurable condition and it makes zero difference that these practices directly negatively impact my life and scare the hell out of me, such observations get down voted and attacked and treated like crazy talk.
I'm sorry for what your social contact is going through.
