and making more people to take care of the old ones is the solution? can they be trusted more than the robots?

Robots can wipe asses or whatever, but they cannot provide care, because care requires more than mechanical actions.

The future you hope for is not less bleak and dystopian than what you try to avoid this way. As always when technology is supposed to bring salvation.

Tech does useful stuff like cure smallpox, provide ample food, central heating and so on. Salvation is more of a Jesus thing - I'm not sure tech is really promising to deliver our souls from sin but might be ok for food and shelter.

Tech cannot promise anything. That's silly! There are people, on the other hand, that go around and preach their gospel, where technology is placed in the center.
