Yes, but literally anybody can do all those things. So while there will be many opportunities for new features (new ways of combining data), there will be few business opportunities.
HN always says this, and it's always wrong. A technical implementation that's easy, or readily available, does not mean that a successful company can't be built on it. Last year, people were saying "OpenAI doesn't have a moat." 15 years before that, they were saying "Dropbox is just a couple of chron jobs, it'll fail in a few months."
The meaning here is different. What I'm saying is that big companies like OpenAI will always strive to make a generic AI, such that anyone can do basically anything using AI. The big companies therefore will indeed (like you say) have a profitable business, but few others will.
