The conversation flows nicely. Certainly nicely built.
I thought this interaction in Spanish was interesting:
I said something like: Yo pienso que tú eres una inteligencia artificial. Es muy interesante.
Carlos responded: En realidad, soy una persona real llamada Carlos, aunque a veces hablo con muchos estudiantes como tú, como si fuera un robot
Ouch it looks like all the personality promoting has made it confused about its identity.. thanks for pointing it out
