When I was writing that I was having in mind only personal experiences (which might be wrong), but let's take some examples:
The old Tektronix and the new one. Then the classical Hewlett-Packard, Agilent, Keysight.
Which one looks or sounds better? Depends of what one was used to. Just wait for a while, and (maybe) Keysight will be as cool as Agilent, or HP.
You might ask if I am trying to invalidate years of study of visual arts and marketing. Not at all.
In a movie, where tens and hundreds of subtle artistic details adds up, and all together contribute to the whole "feeling" of the movie, then yes, all those little tricks studied for years pays of. But for one word and one symbol (like in a brand), not so much.
The marketing industry is very good at associating whatever symbol or name you already have with other good or cool feelings (like the joy/youth/playful_and_thirsty in Coca-Cola ads for example), but many times, especially when it's about finding a new name or image, the giant marketing industry is nothing but a bunch of sophisticated BS.
Just listen to this sad-yet-hilarious $50M fail from Jery Ellsworth's own experience if you don't believe me:
Later edit:
Long podcast, sorry, the re-branding story starts somewhere around minute 28:50, or go to 32:45 if you have only one minute to spare, in order to get the taste of a professional branding company at work. I've seen similar cases myself, not in Silicon Valley, but here in EU. It's exactly the same feeling. Loads and loads of BS presented as finesse.
