I think he means the written language doesn't work well for acronyms and other shortening. Each character is already so much work. You could never get words like SNAFU.
Chinese shortens words by replacing two-character words with one-character ones, e.g. 北京天津高速铁路 (Beijing-Tianjin High-speed Railway) is abbreviated to 京津高铁 (lit. "Jing-Jin High-Rail).
Yes, but that is still 4 characters = lots of strokes. Also, not everything can be reliably shortened this way. You can't get the kind of shortening you can with things like "TNT", "DNA". And what about when there are no two character words to be shortenened? Like WTF.
