That civ4 mock is pretty serious.
No-Code/Visual-Design type tools are great for managing assets and game editors are probably the best example. For 3d stuff, It’s definitely possible to connect to a remote instance of Blender and script it via a repl.
The reverse repl thing (swift ui) is really cool and it’s very attractive for designers/beginning devs/people that want a more immersive experience but I dunno… I don’t feel like it’s that great a feature to have the cursor move to the line when you click on a box on the editor. What happens if you are generating a bunch of boxes by code instead of drawing each box out on the gui? Where does the cursor move to then?
RAD tools for databases are pretty cool too but It also depends on what you’re trying to do. What happens when you want to stream db events via a custom protocol to the ui? I’m not sure how the tool will help.
Visual-tools meeting 6: general monthly meeting may have people doing something similar to what you’re talking about - but with data visualisation as opposed to guis.
