So my question is, will there ever get a technology that you can recover your bitcoin from when you have been scammed. In my opinion, it can help many people that lost their bitcoin for the long term and appreciate the value more than before.
Two things you're combining here OP,
1.Recovering your bitcoin from a lost or wrong address, which is not possible because bitcoin transactions cannot be reversed and any coin sent to a wrong address is gone for live, except if it was being rejected by the nodes, but once confirmed, they are irreversible, the coins are lost and such coins are believed to be released back to the network and splitted that we may all benefit from the effect on the market price, which is all about what your title says.
2. Secondly, going by the quote I made from your post, here above, you're digressjng further in talking about being scammed, which is a different case also entirely, if you're being scammed and your asset is taken away from you, then it's a different case, because you don't need the network to make a reversals of the transaction made, but instead, the duty of the security agencies to investigate on the case and recover back the money stolen and each of the amount being accounted for, but it's such a heartbreak that the government don't returned such from seizure, instead they keep it as part of their portfolios and even spent from it.
