Much like vaccination, it's impact will be down to how prevalent fixes are. If you're not patch but everyone else is, it won't likely be exploited much in the wild. FDIV was a mathematically incorrect operation.
Meltdown is much more like the F00F bug - for which there was a work around, and no recall.
No, it is not. There were a number of F00F bug workarounds [rcollins.org], all implementable at OS level and with negligible (if any) performance hit.
Meltdown is nothing like it. The performance impact depends largely on the load type the CPU experiences, but it is estimated to range between 5% and 30% - which is terrible.

You know, he's not wrong. This is, in impact, way bigger than Intel's FDIV fiasco and that ended up in recalls.
