First, this is really great. I&#x27;m looking forward to seeing how it works in practice.<p><i>&quot;We plan to do this for a long time.  If some of these projects take 25 years, that’s perfectly fine with us. &quot;</i><p>Building an <i>institution</i> that supports this kind of long-term commitment is going to be a challenge. While there are plenty of organisations that work over those timescales, very long-term <i>projects</i> seem to me to be unusual - and not just because results are increasingly expected in the short-term, but because 25 years is about half of a long career and few people (imo) have the commitment and self-belief to embark on such a project. I can think of some, like SETI [1] and Mass Observation [2], but they tend to be highly distributed. The danger might be that you end-up with something like the Institute for Advanced Study [3] with its debatable productivity record.<p>Nevertheless, this is a massively positive announcement from YC. We need more stuff like this.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Search_for_extraterrestrial_intelligence" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Search_for_extraterrestrial_in...</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Mass-Observation" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Mass-Observation</a><p>[3] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Institute_for_Advanced_Study#Criticism" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Institute_for_Advanced_Study#C...</a>
