Unless companies make bespoke software tools or SaaS programs for different industries that use agentic AI, which I think is likely since there are many industry-specific software tools made externally in B2B contexts, AI and predating AI. There's already paid AI tools everywhere of debateable levels of value and usefulness.
Non-programmer employees being expected to build agents may happen, but there's too much of a value proposition for external companies to forgo it. And there's also a possibility of companies bringing in contract programmers who develop those agents, or using in-house IT departments.
We're currently in a really awkward early adoption phase where end-users are being given open-ended LLM and agent tools to just play around with, and with or without a crash, I do see the industry shift toward better software integration where the end-users won't have to adopt this makeshift developer role. And then the adjustment period would be simple as AI tools start to look more like regular software that's quick to pick up with minimal risk of skills gaps or being left behind.
I could be wrong, of course, but that's basically my read on the situation.
