For something this large, it likely isn't "encapsulated" like a normal chip. I'd almost expect it to be left more or less "bare", mounted to some kind of very stiff PCB-like material (which is probably bonded to aluminum or something). Then wire bonds from the "chip" to the PCB.
The whole thing is probably then immersed into some kind of non-conducting fluid (mineral oil or fluorinert would be my two first guesses), probably vertically to take advantage of thermal circulation. Mechanical circulation of the coolant would likely be very gentle so-as not to disturb the wire bonds, unless they have something special to keep them in place (maybe the bonds and edge of the chip are encapsulated leaving the center bare?).
All of this is just guesses from somebody not an expert or even ever touched stuff like this, just based on what little I know about how normal sized chips are packaged.
Here's a few things GNUnet replaces and why it's better:
Bittorrent is replaced by GNUnet "filesharing", it's trackerless, it provides a search function, users can adjust their level of anonymity for publishing, downloading, and searching.
DNS is replaced by "GNS", it covers the "decentralized" and "secure" points in Zooko's triangle, it a pet name system.
VPN is replaced by GNUnet VPN, which is just VPN over GNUnet so it can take advantage of the p2p network.
TCP/UDP/SPDY/QUIC is replaced by "cadet", takes advantage of the p2p network.
There's also a DHT.
And there's lots of other stuff that's in-progress.
We should maybe include a "GNUnet in 5 minutes or less" on the website. The old LEGO analogy is nice, and lynX did a great comparison here: https://secushare.org/img/stack-comparison.png
We don't really need the ISO OSI model here, but even this can be added, as we've already used it throughout the years to compare to the GNUnet stack.
Do you mean the Drake equation? The relevant factor would be n_e "the average number of planets that can potentially support life per star that has planets"
The thing with the Drake Equation is that it sort of plays with our lack of intuition around extreme probabilities. It includes some terms around the size of the universe and the number of planets that we (now) know are huge. And some others that we suspect aren't all that unlikely (like evolution of "life" in some form or other). But then it includes terms that, given a sample size of one, we really have no idea about--and just because 1 in a trillions odd seems a hugely conservative guess doesn't mean it's reasonable.
