Aldo you sure know how to demoralize someone. Whats with all the pesimism?
Realism is not pessimism. This may only be relating to a game, but you should be prepared for this level of basic consideration for any debate in life. Apply the same shallowness of thinking to a real, non-trivial problem and you will be screwed - hence why I point these things out here.
I did not say such and endeavour had 100% chances of succes. But still lets not forget we managed to get a couple of shivan fighters to work. This means that the GTVA does posses some kind of shivan tech understaning.
Show me one FS2 ship build using Shivan technology? We have seen a couple of fighters, jury rigged to work. I can drive a car - it doesn't mean I understand the thermodynamic and engineering principles required to build a new one from scratch.
Also for language and stuff we have the ETAK project dont we?
do we? Even if ETAK works, that has no value whatsoever for interfacing with technology. In order to have something to translate, first you have to obtain it. Moreso, ETAK may very well have been 'audio' (the command brief references to Shivan communication seem to bear this out); that's different from written language (a cursory glance at the problems of speech recognition and text-to-speech indicates this, and that's on a level of highly advanced linguistic knowledge of the whole language and its grammar).
I know they didnt manage to get the engines working but at least they managed to get everything else working like targeting computers sensors etc. This all sugests that shivan tech and GTVA tech is not all that diferent. Sure shivan tech may be more advanced but the tech language is not that different as you asume.
See above. Additionally, there is a substantial difference between a fighter and computer system. A fighter will have certain common requirements - like engines, weapons, power sources, etc. A computer system doesn't - it can be build in any way. Imagine the difference between an abacus and a pocket calculator. More importantly, imagine someone at the level of an abacus trying to understand the precise operation of a pocket calculator... and even then, the abacus user has numerical knowledge (equiv. to language, grammar, structure - the background of the device) applicable to their study in excess to that of our hypothetical GTVA/Shivan situation.
