Would you go to a foreign country and sign a work contract based on the LLM translation ?
Would you answer a police procedure based on the speech recognition alone ?
That to me was the promise of the science fiction. Going to another planet and doing inter-species negotiations based on machine translation. We're definitely not there IMHO, and I wouldn't be surprised if we don't quite get there in our lifetime.
Otherwise if we're lowering the bar, speech to text has been here for decades, albeit clunky and power hungry. So improvements have been made, but watching old movies is a way too low stake situation IMHO.
- your mother visiting your sister (arguably extremely low stake. At any moment she can just phone your sister I presume ?)
- You traveling around (you're not trying to close a business deal or do anything irreversible)
Basically you seem to be agreeing that it's fine for convenience, but not ready for "science fiction" level use cases.
