Você está correto, é a medida de um homem. Os dados estão sendo solicitados a se submeter a um procedimento perigoso para o benefício da Frota Estelar, e questionam por que seres biológicos não estão sujeitos a isso.
De link . Nota: a conversa final (como mostrado na resposta do @PeterSabers) difere um pouco do roteiro original.
PICARD It's precisely because you are a Starfleet officer that they can. We take an oath to serve. In this case this is the form your service is taking. DATA Sir, Lieutenant La Forge's eyes are far superior to human biological eyes, true? PICARD Yes. DATA Then why are not all human officers required to have their eyes replaced with cybernetic implants? Picard is utterly at a loss for words. We can see the confusion on his face as he struggles for an answer to this unanswerable remark. Data rises with great dignity. DATA (continuing) I see. It is precisely because I am not human.
