Low-code has been promised for the masses for ages, and has barely fulfilled that promise. I have seen a lot of non-techies come up from solutions, from websites or eCommerce stores, to little Zapier integrations, to a simple CRUD system with Airtable. Low-code is great for these use cases, but they're really simple. Anything beyond trivial complexity, these people generally stall and they need to hire designers or programmers. Hey, it's fantastic for that first 1% and that's already a lot, I'll give you that.
I actually think low-code will see a resurgence serving "almost technical" people such as tech business analysts, and also, drum roll... programmers. There is a current generation of maturing low-code tools (ex: Retool, PowerApps, Plasmic, Builder.io) which allow tech people to combine low-code and code as needed and which programmers may actually find attractive.
As for AI (ex: GPT), the main output it provides is code. It's nearly impossible to operate it at present for code-generation tasks without knowing how to code. Yes I think it's inevitable we will see a tool that blends current low-code graphical programming with NLP inputs. But it sounds very complex to make and I think it is likely to face the same base problems that low-code has.
