This comment annoyed me so much I had to get an actual keyboard to respond.
First off, the concept of "good taste" is much, much broader than only applying to clothing based fashion. You can have good taste in practically any field that involves any amount of creativity/choice: cooking, painting, writing, music, programming, video game design, etc, the list is practically infinite.
As such, the idea that most "engineers and technical persons" don't "understand good taste" is incredibly silly. It's entirely possible, perhaps even probable that the average programmer lacks good taste in terms of fashion, but that says nothing at all about good taste in other areas.
Secondly, having good taste and being able to apply it is also wildly different. I can recognize what looks good in fashion or paintings without being myself able to achieve that.
Thirdly, there's really no such thing as a "normal human". The longer you live, assuming you're willing to actually examine your experiences, the more you'll learn that the trite expression "everyone is unique" really is accurate.
Just as a semi-random example, it might be tempting to think of watching football (nfl) as "normal". According to a quick google, the average nfl game gets like 17-20million viewers, and even assuming that's accurate/all unique people/etc, it's a very large number in absolute terms but its less than 10% of the population of america.
So if you took a random group of 100 americans, something like 6-7 would have watched a football game last week[1]. Now that's still many times larger than the number of people who wrote code last week, but it's not some kind of overwhelming majority that "everyone" does.
[1] Yes these numbers are extremely imprecise, it's rhetorical
