In theory. I doubt that enough people are already here because only few really want the change.

Now for the next step?

Check what people want. If there are huge differences that prevent a common goal, split the group.

Then have a debate on what to do next in each group, vote on it and start.

I would start with some business to make money and to develop a common culture and ethics.

Expand until there are enough people who can live in one place. Then create that place and move there.

Expand further until the knowledge and the location for a city from the future is available.

Then build the city.
