This statement is incorrect.then I realized NO ONE CARES
"Some don't care" or "Many don't care" are probably true, but there are plenty of others that do, me included.
For example if having a conversation or argument with somebody about some modern AMD CPU or motherboard, I look if the person is also having an AMD computer.
If they list some i5-2500 it may seem they have little or no experience on how Ryzens work, so I might be looking at somebody else's experience instead ...
There might be more reasons to have the specs listed, not just for bragging rights.

Actually, it would be even more interesting to have a SEARCH for those specs.
For example, locating people that list a certain gaming mouse or a certain motherboard, to ask for specifics that only those people having that product might know.
