AMD is supposed to already know that since they make Wi-Fi and 5G chips too and have expertise in wireless technologies and video and audio processing. Not implying it's "wrong", just pointing out that it's funny that they find that LinkedIn post "insightful". It's highly likely that it's simply the communications intern or employee who forgot to switch accounts.
You usually wouldn't find a car company finding a post about combustion engines in layman terms insightful.
The post is by an AMD employee, and the "insightful" button is not to say that you learned anything from this necessarily. Just that the post is, well, insightful. In this case, they see that he's an employee who made a post sharing knowledge about something and are using it to show support. They're basically using the company account to back him up by confirming he knows what he's talking about. Like you do when you confirm peoples skills etc.
I don't know about car companies specifically, because I'm in IT, but 99% of my feed is programmers sharing basic programming stuff that is liked by other programmers who obviously already know, or power users sharing OS specific tricks that everyone else who liked definitely also already knew. That, and invitations to seminars on cyber security. It's like a big ego stroking fest where the only way to make your presence known is to make posts like these, so everyone else who knows the same stuff you do can look at it, stroke their beards and say "hmmm, quite, yes, yes" in a very sophisticated manner.
Insightful doesn't mean you learned something from it. If you say something is insightful it means... It's definition really "having or showing an accurate and deep understanding; perceptive." You can understand something and still say it's insightful.
