The fact of the matter is, a person working with a bunch of agents is a lot more productive than just a person. It makes research faster. It makes experimentation faster. It makes output cleaner. And this is true across many disciplines, not just tech.
Also, it is a skill. Yes, anyone can chat with an LLM. But understanding the optimal work flow for what to delegate and what to do yourself is difficult. Understanding the need for precision in the language used, and learning how to elegantly phrase things that were previously just abstract thoughts is absolutely a talent that can be refined.
If i had to guess, I'd say we'll probably see major breakthroughs across multiple disciplines within the next decade, largely because researchers and engineers can cover much more ground individually now, freed from the slow moving coordination mechanisms that team dynamics require. Pretty good for "spicy autocomplete" as you put it.
