The difference between a futurist and a futurologist
I always thought that Futurologists were like Hari Seldon and futurists were like Kevin Warrick at his worst.
One makes scientific predictions and tries to use less assumptions/ more data to predict likelihoods with timescales, whilst the other churns out very nebulous statements based on popular trends and full of gaps in technology progression.
Futurologist = "By the end of $decade, we will likely have a variation on $theory to enable a system of global communication. Likely candidates for the tech used will be $tech. This could be exciting"
Futurist = "in the future, we will have the ability to communicate with the rest of the world and it'll be awesome, but I have no real details. That's small stuff."
