The cost of broken x86 is already significant and rising rapidly...

"As to the future ISTM that the determining factors over the next few years will be the ability to mitigate the likes of Meltdown in Intel/AMD architecture* in the next generation of products and the adoption of ARM in workstations in a configuration consistent with those of servers."

I think the deciding factor will be chip errata. Case in point Xeon errata have been consuming a serious amount of man-power, money, and lost production. It's easy to point the finger at the validation processes, but I think the actual root cause is the ISA. It's too big, too complex, and in many areas too poorly defined. It is a money pit for validation and remediation.

Cleaner ISAs with cheaper more reliable hardware will tell in the end.

YMMV :)
