The hardware can’t really be repurposed, it is build for an very specific use case. The AI accelerators for example can’t be just used as graphic card, even if they use lots of the same parts, but the whole layout and interfaces are completely different. We are speaking of highly integrated hardware with extremely specified firmware that is guarded by sophisticated encryption layers.
Even if some hardware hackers find ways to crack, modify and repurpose some of it, then nothing on the large scale will change. Such modifications would be extremely difficult and time consuming (aka expensive) and only a very small percentage of people have the skill, knowledge and/or the equipment do do something like that.
We are far away from the 80s where it was easy to tinker with hardware.
