What's up with Alan Kay's STEPS?

Question

Operating Systems

I read that Alan Kay was going to write a new operating system from scratch, only a few tens of thousands of lines of code. What is now with this project, and where can I see the source?

Answer 1

Here are all the reports: www.vpri.org/writings.php
The last STEPS report was in 2012.
www.vpri.org/pdf/tr2012001_steps.pdf
Why do you even need these sources? Why are they so interesting?
