RISC-V is not going anywhere as it is not a single player. If it disappears, it will be because it has been replaced by a better alternative. ARM is not going anywhere for a while. It dominates the mobile and embedded markets and is making in-roads in others. If it eventually gets displanted, it will be by RIsC-V or its successor. X86 is vulnerable, more vulnerable than the other two. Taking it down is going to take a lot though. I would not bet against it. The biggest problem is that it is master of an ever shrinking empire. Even if they never lose it, they may matter less over time.
