I believe in Jesus Christ and he offers the prospect of eternal life, so yeah Christ is an example of a homo deus.
For those who don't believe in Him, their way of achieving immortality is through science. I would not go into the ethical aspect of this discuss. However, I will like to state that a lot of bad things still happen in this life, so whatever it is good or not, people are still going to strive for immorality. A lot of big companies are already investing heavily in it
