AMD Zen 2 has Hardware Mitigation for Spectre V4
AMD in its technical brief revealed that its Zen 2 microarchitecture has hardware mitigation against the Spectre V4 speculative store bypass vulnerability. The current generation "Zen" and "Zen+" microarchitectures have OS-level mitigation. A hardware mitigation typically has less of a performance overhead than a software mitigation deployed at the OS or firmware level. In addition, just like older generations of "Zen," the new "Zen 2" microarchitecture is inherently immune to Meltdown, Foreshadow, Spectre V3a, Lazy FPU, Spoiler, and the recently discovered MDS vulnerability. In comparison, the 9th generation Core "Coffee Lake Refresh" processors still rely on software or microcode-level mitigation for Spectre V4, Spectre V3a, MDS, and RIDL.

Anyhow, nice to know that those two are now hardware-mitigated.
But I digress ;)
It is not only the US media. Is the cultural globalization tendencies overall, it doesn't happen only with English. It is our human nature to be lazy at everything.
It is totally fine that we ask for uncertain things here and we are not afraid to do it so, and someone helps and sincerely explains.
Please do not take what i say too seriously or literally.
Note: I learned english in the American Alliance of Montevideo, Uruguay.
Back to the topic, I can't seems to figure out why a giant like intel has these vulnerabilities in their CPUs, and AMD doesn't....
AMD had their own share of vulnerabilities, but Intel is still the bigger target because of their larger market share.
Everybody is correct!!!

Why does AMD need less time to mitigate Spectre V4?
The real definition of Naturally Aspirated means to be non electronically fuel injected ie: Carburettored like almost all pre 1970's cars
You get a variety in designs, and a choice as a consumer when they find vulnerabilities like this.
Competition is necessary in this market.
Intel already resolved Spectre V4 with a new stepping for months.
