By contrast, your subconscious produces vast quantities of predictions, most of which are necessarily discarded as junk or inactionable long before they reach your conscious brain.
It sounded to me like the author had gained over a decade of experience of the business expense/benefit associated with social media, and in conversation with others, was able to reveal to themselves what they already knew to be true: they were not benefiting from their social media presence, and that it was actively subverting their dopamine circuits towards “likes” over “purchases.” Instead, they benefited primarily from personal relationships formed in other mediums, and spending time on social media was a distraction to, not a building block of, their business.
Really?
I suppose you believe advertising doesn't work and the billions spent on it are unjustified?
Look at how brains work. Stimulus response. Reward pathways. Millions of years of biology and chemistry.
Or just read a book on positive dog training. I recommend "Total Recall" by Pippa Mattison as it explains how tiny little reward lead to behaviour that is utterly fixed no matter what distractions come along. ('The power of habit' by Charles Duhigg is the equivalent book for humans)
Just because you use social media for business doesn't mean it can't affect you.
Again, read a book on dog training. It's all laid out very simply.
