> I don't see anyone cooking up the next photoshop and selling it at $3/month.

That's not the situation we're talking about though. It's someone saying "hmm, I need to edit this picture. Can I get ChatGPT to do it?" where 3 years ago they would have had to buy Photoshop and learn how to use it.

Similarly, if they need a tool to batch-convert a thousand images, they're getting an LLM to construct the specific tool they need in a couple of hours and then running that, rather than buying a software product that can do it.

You don't need a whole dev team to build a one-off tool for a specific job, which is probably 90% of the demand for those software products. LLMs are becoming the general-purpose tool for a lot of use cases.
