Microsoft Fabric - How is it? Is it worth getting into?

I recently saw a video where they were talking about Fabric Apps and how that would basically replace Power BI. They had it connected to some AI, would provide it with a link to a data model and it would spit out a fully rendered Fabric App page. The demo was decently impressive, as most demos are, but demos always lack that "grit" you see in normal day-to-day development - those scenarios where true experience and problem solving skills saves the day. The app thing mostly caught my attention because I have some experience with Power BI specifically, but the topic is also about Fabric in gener
