Except no, AMD 100% played follow the leader with technology like CUDA, NVLink, and tensor cores.
Even paying paying someone in academia to get s** to work on their hardware is yet another example of follow the leader.
What exactly do you think is coming? I think the biggest threat is one or more Chinese companies catching up on both hardware and ecosystem in the next half decade or so myself, mostly because of the state level support for making that so. But I absolutely don't expect an x86_64 moment for GPUs here given past results and the current bias against software in AMD's HW culture. Convince me otherwise.
