I'm afraid that Intel will eventually be left alone.
I think that today it is increasingly less relevant that Intel is left alone. What I see in a few years is that x86 will not have a monopoly on the "PC" but that other players will appear and may even be strong.
On the one hand we have ARM which is currently making do in mobile devices. ARVv7 is timidly entering the desktop since, apart from Raspberry Pi which is a very basic board with very limited power, there are a lot of alternatives for less than 200€ that if they don't match, they exceed in performance the x86 platforms of the same price. And when aarch64 becomes popular, I am sure that a lot of options will appear to build a desktop with a very decent power, at a low price and with moderate consumption.
On the other hand we have RISC-V, which although it is nothing more than an ISA, some heavyweights of the industry have shown their interest which indicates that it is possible that the architecture will eventually materialize.
Regarding software compiled for x86, with Microsoft's ARM tablets we saw how "fast" and "easy" it was to port a complete operating system and key programs to ARM. On the other hand, Valve has already ported the Source engine and some games to ARM to run on Nvidia's platforms (I can't remember the name right now).
So if Intel is left alone in x86, I don't think it will be a great tragedy. Moreover, it may be that this makes new and interesting options flourish apart from the veteran architecture.
