Korean doesn’t reduce typing compared to English from my experience. What looks like a “character” is actually a syllable block called “eumjeol” that’s made up of consonants (moeum)and vowels (jaeum). You can’t have a vowel only syllable either so you always have to pair it with a null consonant no matter what (which kinda looks like a zero: ㅇ) and while nouns can be much more concise compared to English, verbs can get verbose.

The main benefit of Korean actually comes from the fact that the language itself fits perfectly into a standard 27 alphabet keys and laid out in such a way that lets you type ridiculously fast. The consonant letters are always situated in the left half and the vowels are in the right half of the keyboard. This means it is extremely easy to train muscle memory because you’re mostly alternating keystrokes on your left hand and right hand.

Anecdotally I feel like when I’m typing in English, each half of my brain needs to coordinate more compared to when I’m typing in Korean, the right brain only need to remember the consonant positions for my left hand and my left brain only need to remember the vowel positions.

It's fascinating and lucky how well Korean fits into a keyboard designed for English. Japanese and Chinese are notoriously inefficient to type.

만나서 반가워요!

What you talked is mostly right and I did not know about typing in Korean, the left-hand side and right-hand side. Btw, Consonant(Jaeum) and vowel(Moeum).

In experience-wise, what you had would be precise.
