X : Why has it not spread further?
Me : It has spread far. These things take time, typically 30 to 50 years. We've barely started.
Me : No. I'm more interested in using mapping in research. I do a lot of teaching / speaking on mapping with @lefep / @DXCTechnology to encourage others ... of course, it's also taught at places like UCL, LSE, Harvard Kennedy etc.
