[s_r_n]

I'm in exactly the same boat as you. I want to help build the city of the future, but as a data scientist, I have no idea where to start.

This is advice I haven't followed myself, but might start following: talk with people who are working on building megastructures--not necessarily in your city--and ask how they got started. There aren't any online bootcamps for how to build a monorail, so "tribal knowledge" is probably the only way to go.

I'll let you know if this methodology works for me!
