It may help to mention in what way the event is conditional. Summer is a rather valuablr time to many who may attend, and some types of back up plans (internship) are hard to make.
The event is conditional on finding 14+ good participants. Applications are looking good, and I'm optimistic, but it's not certain yet. We will try to finalize things as soon as we can.
CFAR will be running a three week summer program this July for MIRI, designed to increase participants' ability to do technical research into the superintelligence alignment problem.
The intent of the program is to boost participants as far as possible in four skills:
The program will be offered free to invited participants, and partial or full scholarships for travel expenses will be offered to those with exceptional financial need.
If you're interested (or possibly-interested), sign up for an admissions interview ASAP at this link (takes 2 minutes): http://rationality.org/miri-summer-fellows-2015/
Also, please forward this post, or the page itself, to anyone you think should come; the skills and talent that humanity brings to bear on the superintelligence alignment problem may determine our skill at navigating it, and sharing this opportunity with good potential contributors may be a high-leverage way to increase that talent.
