LUCA's descendants were able to go to every possible life niche on Earth and displace all other types of life? That makes very little sense.
It makes perfect sense, you explained clearly how it could happen.
The reasonable way of looking at it is, "What is the probability of that happening?" That's a scientific question.
How? Not technically, but from a business point of view.
From a technical point of view, you can also ask why would you ever make your compiler target LLVM bitcode. There are better options.
It'll be about 3-5 years but more or less. That's how long analysts think the AI build out will last.
Which analysts?
... is that it's a protocol designed and built by someone who knew what he was doing (Linus Torwalds) resulting, among other things, in the fact that migrating your upstream Git repo away from a commercial service like Github takes something like 20 seconds, if you're having a slow day.
The difficulty of migrating away from Github is when you've built your entire deploy pipeline and QA process around it, which is what a lot of companies are doing lately.
More cylinders does make for a smoother engine without complex harmonic dampening, which the Japanese have decades of experience in doing exceptional at.
There was a big scandal about smooth submarine motion during the cold war. Toshiba makes the quietest refrigerator I've ever heard (42 db iirc). Can't hear it in the next room.
Among widely available fonts under OFL, GNU GPL for Fonts, or other free licenses, not many of them cover the 2,100-odd Jouyou (regularly used) kanji and 1,000 name kanji that BadDreamer mentioned. It's a lot easier to make a font that covers 100-200 characters from two alphabets, such as Chilanka that covers the Latin and Malayalam scripts in a distinctive and dyslexia-friendly handwritten style, than one that covers 3,000 different kanji made of 600 radicals (as iggymanz mentioned) with manually-tuned slight variations to their shapes to make them fit next to each other in a character.
you could still [write Japanese] in native language with a manageable scope by sticking to the phonetic scripts.
Exclusive use of kana (Japanese phonetic characters) was common in games for MSX, Famicom, and other 8-bit platforms. The one problem with that is the sheer number of homophones in both Chinese and Japanese, words spoken the same and written differently. Kana normally don't even distinguish which syllable a word is accented on, which would be like writing Chinese without its tones. Yet somehow Korean avoided this and switched from Chinese characters (Hanja) to a suitable phonetic alphabet (Hangul).
