Re: TIFKAM redux...
Most of us still use keyboards with key layouts that are a design solution to the problem of mechanical typewriters jamming up.
Most of us still use an alphabet designed for engraving epitaphs on rocks with a chisel. Steering wheels were borrowed from ships and haven't evolved in any meaningful way since they were first adopted (except for power assistance allowing them to get smaller).
Just because a solution is old and entrenched it does not necessarily follow that it needs a rethink, particularly when it is ubiquitous. One can argue that Kanji is a more efficient encoding scheme than the Latin alphabet but it won't make the slightest bit of difference. That is a solved problem. You can evolve fonts and over time maybe work in some pictograms like "emojis" and ";)", but "radical rethinking" is a counterproductive waste of time.
