That is an extreamly stupid statement for them to make if it is true
Pot and kettle spring to mind.
Anyone who has programmed micro's knows ..... you are searching for a way to develop faster without needlessly burning off write cycles.
That way is called thinking about what you are doing. Us old timers learnt to program when you could only physically get one run a day. It made you think before you committed something to code. Therefore the proportion of "right first time" is quite high.
As the arduino provides for much larger programs, the cycle of "make a change, write it, test it, repeat" gets counter productive.
Ye it does if you don't know what you are doing, the easer it gets the less productive you are.
(And a good reason people will switch from a stamp, i might add)
