Agentic AI is interesting because it has the opportunity to create competitive advantage that other companies cannot replicate. And that's the promise. Yeah, you can pay someone to build a custom agent, but it's $50k+ plus maintenance for one agent - and it just doesn't scale. It's way cheaper to train up your team who can build many agents.
Companies that delay or avoid training their teams are in for a bad surprise when a new company built around the technology enters the market. It will be one an existential problem that will result in job loss (think Amazon vs brick and mortar).
My general recommendation for workers is to get trained up on agent building - then go get a job at a company investing in their people, because those are the places most likely to survive.
