It's like commercial success is a three step tragedy:

(1) solve 1 problem well

(2) pivot to trying to solve all problems for all users, undermining (1) but chasing mass adoption

(3) pivot back to solving 1 problem again, this time for a very specific whale customer with very specific needs, undermining (1) and (2)

I would say Arduino is at step (3) and RPI is at (2)
