Agentic LLMs are, in a way, an attempt to commoditize entire service classes, across the board, all at once.
Personally, I welcome it. I keep saying that a lot of successful SaaS products would be much more useful and ergonomic for end users if, instead of webshit SPA, they were distributed as Excel sheets. To that I will now add: there's a lot more web services that I'd prefer be tool calls for LLMs.
Search engines have already been turned into features (why ask Google when o3 can ask it for me), but that's just an obvious case. E-mails, e-commerce, shopping, coding, creating digital art, planning, managing projects and organizations, analyzing data and trends - all those are in-scope too; everything I can imagine asking someone else to do for me is meant to eventually become a set of tool calls.
Or in short: I don't want AI in your product - I want AI of my choice to use your product for me, so I don't have to deal with your bullshit.
