Many in the SciTech world who would shrink at even the thought of legitimizing Psychoanalysis should know that Freud only developed his psychological theory after trying and failing to create an entirely physical explanation for cognitive processes (Cf. "Project for a Scientific Psychology", Standard Edition I, pg.283).
The entire field of Psychology would not exist if not for this failure, a failure which is also an admittance that something as dynamic as the internal processes of the mind can in the first place only be understood in a social context, and that socio-psychological context is always in a constant flux. So the first thing to analyze, then, is what social processes, unique among humans, lead to the development of the psyche? Clear as light in day, the first word ever spoken by every person on this planet is a simple bilabial plosive repeated with an open-back vowel, "mama", or any of the many other similar words which all are formed in the same way and all for the same reason, its the only word a baby can articulate, and the first thing a baby learns is that when it speaks this word, milk and comfort arrive. So for Freud, everything goes back to the mother. The further one gets from that original source of comfort, the more complex means they employ to try and return, ceaselessly failing, always repeating the same thing over and over again. This is the origin of all language, all logic, and all of human society for Freud.
Certainly, people still feel the need to see a therapist, and yet there is some hope among people who work in AI that following along the path we have been, one day the AI and Neural-Networks will somehow "match" human intelligence, when humans were never truly intelligent in the first place and always have had to employ some means of artifice for productive labor and the transmission of knowledge. No true advances will be made until we recognize that AI is an outgrowth of human logic and human social labor, which, at the moment, somehow seems as though it will dominate us, even though it is our own creation.
