My kids get erroneous responses from Alexa. This happens all the time. The built-in web search doesn't provide correct answers, or is confusing outright. That's when they come to me or their Mom and we provide a better answer.

I still see this as a cool application. Anything that provides easier access to knowledge and improved learning is a boon.

I'd rather worry about the potential economic impact than worry about possible hallucinations from fun questions like "how big is the sun?" or "what is the best videogame in the world?", etc.

There's a ton you can do here, IMO.

Take a look at mathacademy.com, for instance. Now slap a voice interface on it, provide an ability for kids/participants to ask questions back and forth, etc. Boom: you've got a math tutor that guides you based on your current ability.

What if we could get to the same style of learning for languages? For instance, I'd love to work on Spanish. It'd be far more accessible if I could launch a web browser and chat through my mic in short spurts, rather than crack open Anki and go through flash cards, or wait on a Discord server for others to participate in immersive conversation.

Tons of cool applications here, all learning-focused.
