So, this is just the viewpoint of a new guy barely even started, but let see if I am clear on this.
Parroting is a useful and healthy tool to use in the begining of trying to form sentience. (feel free to jump in anywhere and correct me if I have got it wrong) It helps to set a pattern for thought and action that the tulpa can then ride off into its own direction. But that after those patterns and abilities are there and the machine gets rollin', parroting then becomes essentially useless?
I almost imagine parroting is like trying to jump start an engine? It might take time to juice up the battery, but after you do you should move to adressing the rest in a different manner.
Is parroting useful at any stage other than the start? And then is it inadvisable to try and NOT use parroting at all, not exactly out of fear but rather just choice of method? Does it stifle progress to NOT parrot?
