I'm envious of anyone who speaks more than one language! I'm one of those awful Antipodeans that never thought they'd need another language, growing up. Conceited and parochial to say the least, and I wish my parents had insisted on at least one language. What are your thoughts on the AI conversation way of learning a language? I see them advertised a lot but I'm not convinced. Every time I've tried to learn a new language I've failed miserably. I am great at recognising words when I read them eg street signs, menus etc, but putting it all together to speak? No freaking way.
You must learn multiple languages, it is NOT optional :)
AI is very good as a trainer and teacher for adults (not good for kids, yet!).
Both Duolingo and Pimsleur(which is very good) uses AI effectively.
