That's true! Jesus is only sharing the truth with his disciples. The rest remain in the dark. I'm sorry to hear that you and your Watchtower buddies remain in the dark as is exemplified by insisting that either Jesus or the God of the Bible is a god - with a lowercase g - and that this God of the Bible has a name Jehovah which you know is an impossible name for the God of the Bible.
The God of the Bible is not against using technology (or faith) to prolong life or to mix with people with different beliefs to those of your own. Jesus himself set example to illustrate this. Jesus also illustrated that it is what we do to alleviate suffering that really counts rather than what we believe.
