With more tasks being automated today with advent of AI (GPT3), the value of quality is enhanced much more now.
AI or bot can do only limited quality work but can easily beat humans in quantity. Hence as an expert in your field you will be valued more because you bring quality. Your uniqueness, your experience will have more value, since no one can copy or generate it.
At the same time quantity will be culled out more and more because of its abundance. And for those who go after quantity, beware of it, as it will hit roadblocks sooner or later and leave you stranded.
Best case will be, to have right mix of quality and quantity as you go along.
