Future of multi-agent LLMs

As individual LLMs become more powerful in 3-4 years, could multi-agent systems with agentic LLMs that respond to each other exhibit emergent properties or capabilities that wouldn't be possible with a single model? What new research directions might open up for exploring these emergent behaviors in multi-agent LLM systems that cannot be achieved with single LLMs that become more powerful in future in terms of capabilities?
