Gadrin!
Thank you very much!
GTL-11 is seen as Traveller TL12, which corresponds directly to the T20 RNA implant procedure.
Perhaps semantics here, but inserting new memories over older ones ("layering"), and replacing & refilling said memories with others is a form of 'mindwipe'.
Psionics? No--Science. Psionics are rumored to be able to do so without the medical machinery to do so. Machines which transcribe or can video-image up such memories information are TL-14+, making them rare.
canon examples are
1) the TL-14 Solomani robot used in court proceedings to adjudicate whether a person is telling the truth,
2) the Ilelish device that was used to "brain tap" a dead scientist in order to discover why he'd been killed--this unfortunate necromancy however can only recall the last 10-15 minutes of a preserved brain's short-term memory recall.
3)The portion of the brain controlling long term memory is known and can be manipulated/ altered by TL-12 medically, wherein we found the basis for the article. Still, it is an injection, and I postulated it is done with an injection of nanites (mini-robots) that carry the RNA data to that location solely and deposit it before dissassembling themselves (1-shot nanites in other words).
There is a risk of failure, and chances for insanity to develop even at higher tech--which prevents this from munchkinism. Only 1 per Character year can be attempted safely without risk of a disastrous anomaly within the human brain & pyschotic results.
In the order of some worlds using the 'mindwipe' technique as capital punishment--e.g., The removal of memories in this defined procedure, the limits of which the GM defines might be complete removal all the way back to childhood & an entirely new life's memories installed to the simple removal of several years removed covering the criminal act, and events leading up to it.
In the order of use for the RNA for couriers carrying data, the same procedure as say the RNA college degree are used--with the check-up 30 days later to see if it took hold.
In a 3rd Imperium with rival Megacorporations and industrial espionage on a level undreamed of in our present day sense, committing data to hard copy and datacrystal storage is still subject to theft.
Using this wet-wire method is (when successfully downloaded mind you--ala Johnny Mnemonic/ Total Recall) more secure--to get the data to you have to steal the entire person, and you could grab the wrong guy/ gal! Downloading the courier's data requires again a Trained/ liscensed TL-12 doctor or a TL-12+ equipped facility.
Naturally criminal skills by less than scrupulous folk, and memory theft 'brain-jackers' can lead to some interesting villainous adventure hooks...
The T20 chapter in the Handbook briefly described these uses, and I attempted to put some flesh to the bones we have.
helpfully yours,
