This is very cool, and at the same time, this is how they plan to lock people in. The moat isn't really in the models, it's in their users and how much they are invested in their ecosystem.

Once you have started working seriously with these tools, it stops being so easy to switch. What are the open-source alternatives to this? How usable are they for non-technical users?

Another comment I have about this is that unfortunately, there is always an LLM in the loop for each prompt. I feel LLMs should automate themselves away, meaning that for repetitive tasks, user prompts should go directly to deterministic, previously built scripts. This would be both a better user experience (more predictable), and a lot cheaper to operate.
