I reckon this opinion is more prevalent than the hyped blog posts and news stories suggest; I've been asking this exact question of colleagues and most share the sentiment, myself included, albeit not as pessimistic.

Most people I've seen espousing LLMs and agentic workflows as a silver bullet have limited experience with the frameworks and languages they use with these workflows.

My view currently is one of cautious optimism; that LLM workflows will get to a more stable point whereby they ARE close to what the hype suggests. For now, that quote that "LLMs raise the floor, not the ceiling" I think is very apt.

LinkedIn is full of BS posturing, ignore it.
