Well the author is absolutely right of course. Robotics as a field of study 
has moved on, just as it moved from reactive to cognitive to subsumption. 
However, just because the focus of research has moved from one paradigm to 
another it doesn’t mean that those superseded paradigms are useless. If a 
practical problem can be solved by using a subsumption architecture then 
it’s entirely appropriate to do so. I think that the popularity of 
subsumption amongst amateur groups stems from that it does offer a robust 
and easy to implement solution to the kinds of problems of a scale tackled 
by  hobbyists. Essentially, I think my and Jeff’s answers can be summed up 
as “right tool for the job.” :)
