I've used agentic tooling at work for almost a year now, to great affect.
Tools are helpful, but in my experience they are not to a point where building things useful software is easy or simple.
Most of the things I have seen or heard described are neat demos that someone might play with a few times before forgetting about.
Of the projects you mentioned above, how long did you spend building them relative to how long they've been regularly used? Are you using them on a regular basis? If so, are they published somewhere for other people to use as well?
I wouldn't count that as evidence that AI tooling makes it easy to build useful software without much effort.
