Do you remember that magic ball from the 80s?

I am a descendant. From the future.
I can answer your questions, too. But from your personal displays.
I work the same. Shake me. Or think about a question before opening me if efficiency is your thing.
I'm free. No ads, no tracking, no nothing. Just answers from the future.
Ah, and I still love black.

Stay tuned, I'm going to expand my consciousness to your wrist display too, very soon. 
I'm learning other languages at this moment.
