View source for Castle in the sky


This page is about the seemingly present belief that: 

first:

* (1) even if one can identify a sensible far term target (see: [[Nanosystems]] [[gemstone metamaterial on chip factory]] [[gemstone metamaterial technology]])
* (2) if there are no areas of R&D where the problem of getting there ([[bootstrapping]]) can be tackled in a targeted way then <br>the identification of the far term target is completely pointless and a misplaced effort. <br> The as sensible identified target is just an unreachable '''"castle in the sky"'''.

'''AND''' second:

* (3) there indeed are no such areas of R&D where the problem of getting there ([[bootstrapping]]) can be tackled in a targeted way 

== Errors ==

(3) Is clearly false. <br>
There are plenty of points to put efforts in targeted development.  <br>
See: '''[[Most relevant R&D construction sites for progress in APM]]''' <br>
Economic viability is likely one of the biggest challenges.

Even if (3) were true that might change at any time. <br>
And in the case of [[gemstone metamaterial technology]] it <br>
would not requite ultra surprising scientific discoveries that go very against what we currently know, <br>
like [[Star Trek]] like "beaming" or "warp drive" or "matter from energy replicators" would require. <br>
This weakens (2)
