What's the word for "obsolete"?

Question

How can I say "That technology is obsolete" in Korean? I haven't found a good translation in any dictionary, and my Korean friends say I should use "그 테크놀로지는 더 이상 사용되지 않습니다". That essentially means "That technology should not be used any more", and is much too different in meaning than simply stating the technology is obsolete.

Answer 1

Your Korean friend is right. It has to be just like how he translated.

Answer 2

Consider one of these phrases:

1. 쓸모 없게 된
2. 시대에 뒤떨어진
3. 구식

Hope this helps!
