OP gave a good example how their workflow was changed, you could argue there are tools that could've done that, but they managed to achieve their goals without them, have something that fits their workflow perfectly, is fine tuned in case of changes, and with a few other tools (Word, Excel, Figma) they can do all sorts of things which would've required a small team or far more (expensive) tools to execute.

To me that is a great example of non-developers using tools to enhance their workflows and with initiatives like from this topic, I can only see that increasing.

It doesn't obviate the need for software, but it greatly devalues software products, as they become reduced to tool calls for LLMs.

This is good for users, because software products are defined by boundaries - borders drawn around the code to focus and package functionality, yes, but also to limit interoperability and create a sales channel (UX being the perfect marketing platform for captive audience).

After all, I don't usually want to play with Word, Excel, PowerPoint, and Figma - they're just standing between me and the artifact I want to create, so if I can get LLM to operate them for me, I don't have to deal with all the UX and marketing bullshit those products throw at me.

I mean, that's what I'd do if I could afford to hire a person to operate those tools for me. That, again, is the best mental model for LLMs - they're little people on a chip, cheaper to employ than actual people.

Or not. Besides, the better AI models can effortlessly generate Latex/Beamer, a far superior solution for typesetting and presentations. Anything than can be done in Excel can be done in Python. Those proprietary tools are a thing of the past, no one should use them anymore.
