What do you think will be the biggest ethical challenge we'll face with advancing technology?

Straight up privacy and loss of personal identity that isn't tied into the public forum.

Data privacy, no doubt. Look at the uproar over data leaks at Facebook and Google. As tech advances, the more data gets generated and it's a goldmine for misuse. So yeah, data privacy and handling - it's the elephant in the room.

Maybe they will force implants like Neuralink, anyone who refuses to take it will be left behind.
