Most other Ais have a very simple

tells us which version you like

and 2 answers are shown side by side and we can chose.

This is a 100% privacy since we only chose style and preference.

and on top, we can train Lumo without compromising privacy

ON TOP: different people different values.

such answer can have, in options, tick box (default off), for Lumo to check "our preferences" since, if we have 95% of everyone saying A, why do the 5% who said B ignored? (mind you, this is 100% of people who voted, nothing about those who did not).

And such values become even more clear if we say 40% vs 60%

But again, tick box in options: are you willing to receive multiple responses to chose from?

Also this is different from the like and dislike since the dislike always ask us to provide feedback while the like does what exactly?

because if that is a voting system, that it's doing the same "good job" as youtube after removing the dislike button.

Anyway. Idea is that there is not enough transparency what like and dislike does, while for this multiple choses, it's more clear since we'll be able to compare 2 or more answers.
