I don't think that is very revolutionary. NPCs are already programmed with complicated dialogue trees. That last tiny step into infinite dialogue is kind of pointless because the NPCs have a role to play and that dictates the dialogue to some degree.

Too much dialogue is also a problem. Game designers like to bury information and side quests in the dialogue tree which makes people want to go through all the dialogue to make sure they don't miss anything.

The revolutionary advancement around the corner will be in the programming space. I see AI being able to take concept art and automatically turn it into a full 3d model, with optimized polygon counts and fully maped contact boxes, etc. I see it being able to take crude drawings and generate high quality art and characters. Likely dozens of versions that can be chosen by the human and modified with voice commands.

As for gameplay, that will allow characters to collect unique damage throughout the game. That would be cool, but also not recolutuonary.

Uploading pictures of yourself would allow the character to look like you. That would be cool, but probably will be severely limited on purpose to limit abuse.
