I respect your feeling/position on this, but I don't understand it...
What feels "dumb" about it?
Is the perception of others towards you when you do this? Because that ship has sailed, people Vlog on the sidewalk and do TikTok videos in the subway, and Facetime their mom or brother at the grocery store or in the mall and have long video conversations with each other out loud..
I'm not saying this to be dismissive. As a GenX'er it took me a while to normalize this behaviour even to myself, but I've accepted now that these kinds of interactions with devices are just everyday occurrences and literally no one cares.
They can be obnoxious for sure, but just using TTS/Siri on your phone is like the nicest version of this interaction I can imagine. ;-)

Not without me giving them the "Have you escaped from an institution" look they don't. And you judge yourself as you judge others. If I were to say "Add eggs to shopping list" on the bus, I'd instantly feel the stares of a dozen people as I look on my phone in shame (That's whether or not I'm alone on the bus). And my shame is justified too.
Yes if it's 100% reliable and I'm alone then I'd have a low treshold. But it feels weird having a UX that works when I'm alone and isn't accessible when I'm not. On your phone you can just enter "eggs" to your shopping list. But if devices move away from the general purpose input UX, then you'd have to talk to it on the bus. And when it's only 90% reliable you'd have people shouting shopping lists on buses...
