As said, it was good/impressive 20 years ago, now it's just what everyone else has. And SK software is a joke, like the linked post elaborates.
I don't know if it changed during the last 5 years, but when I was there I wanted to use Google maps for navigation and it looked like shit, so after some digging around I found because apparently there are some SK patents that prevent Google from using a lot of modern tech. So no wonder SK people compare that to naver and think their IT tech is top notch, but if you compare it to the "real Google", it's a joke.
It's the same in China actually, but there you simply can't access the western counterparts at all usually.
