>Do you think the last humans to die have already been born?

Definitely not. Everyone will still eventually die, even if they can no longer die of natural causes. Now instead of a graceful demise at the end of a long life, we'll just die in gruesome ways via accidents and murder.

And if you are buying into the transhumanist obsession of a digital eternity in which you transfer your consciousness into a machine, well, I've got bad news for you... it won't be "you", only a copy. You will still experience death the same exact way as you otherwise would.

Not to mention, your digital consciousness would still be susceptible to death via viruses, destruction of data infrastructure, etc.

Death will come for us all, mercifully. Eternal life would become mundane rather quickly.
