>>73520541i also miss it, and the errors like "three three three...", etc. But it's very possible that most people would have gotten tired of it, had it persisted. And the upgraded LLM brings some great things (like less delay and more coherent conversations).
A possible way to have our cake and eat it too would be do some streams that utilize neuro V1 (Hiyori), as a 3rd character along with Neuro and Evil. Seems like most fans already interpret Hiyori as a separate character in the collective head-cannon lore. And it'd be a good reminder of the old tech, which will make the modern tech more impressive.
