I think there's some confusion about this project, since the article doesn't go into to much detail about what it actually is, apart from some high-level technical highlights. My understanding (which is potentially outdated) is that Angstrom is a collaboration effort between different groups who are trying to combine their separate research into a larger project.

For the criticism that the project will "fail", I think there's some merit. Will this produce the next computation system that the world uses? Probably not. Will this push the boundaries of engineering and improve on the state of the art? Almost certainly. And due to its scale, and the fact that Angstrom was created by combining multiple separate projects, there's also room for individual projects or ideas to succeed even if others don't.

My background is that I worked on the FOS project, which is the part that is most related to the title of this post. If you were looking for more technical meat, I encourage you to check out the project page: http://groups.csail.mit.edu/carbon/?page_id=39
