I actually found that quite reasonable. E.g. they were using it to sort and filter data, just like people today use llm's to write their R script and (avoid having to) figure out how to invoke gnuplot. I'm sure somewhere in that computer it's still invoking gnuplot under a century of vibe-coded moldy spaghetti code =P
I don't remember where else they used voice, they had a lot of other interface types they switched between. Tried searching for a clip and found this quote:
> The voice interface had been problematic from the start.
> The original owner was Chinese so, I turned the damn thing off.
So yes, quite realistic :-)
