Together with Brett Victor his Inventing on Principle, I usually show this https://vimeo.com/140738254 to people when explaining my daily existence and the unfairness of it (as in; some of us have these ideas and yet, my CPU cores + memory are overloaded doing trivial db queries to do code completion and rendering HTML because that is what we write GUI's including code editors in now :).
I sympathize with the frustration! It's debilitating to know that there is a better way to program something yet you can't use it because it hasn't been implemented yet. I mitigate the pain by spending some time every week working on my own ideas of how computers / programming should work. Some of these ideas are very similar (at first glance) to subtext / chorus. I knew I couldn't be the only one thinking like that.
I love programming with computers still (and have so for the past 34 years); the ideas set forward in these videos and implementations do give the feeling we might get somewhere. I myself only write tools for specific projects. I hope I get a chance of distilling something more generic from that some day but that might be simply too hard. As for Alarming Development, I much liked Subtext & Coherence (where did that site go? [0]); from what I have seen Chorus is a more high level approach and very curious to try that out even though we have not seen much yet.
Do you know of others?
