Glamorous Toolkit (https://gtoolkit.com) by feenk, which embodies the thesis of this blog post, is in my opinion the most exciting working development environment in decades. I think in 5-10 years people will be pointing to it as having a huge impact on the industry.

I implore anyone serious about changing how software development works to digest Andrei Chis' thesis Moldable Tools: http://scg.unibe.ch/archive/phd/chis-phd.pdf

Once you understand the consequences of reducing the cost of specialised tool development by orders of magnitude, it becomes obvious that a qualitative change in experience follows, that brings us much closer to what people like Engelbart were searching for.
