Immortality.

Don’t even try all the lame excuses about why it is a bad thing. You know who comes up lame excuses? People who are mortal.

• I will never get bored
• I will accept that everyone I know will eventually die
• I am not worried about being trapped in a hole or something because fuck it I will just carry around a collapsible shovel
• I am not worried about heat death because I will just solve entropy Asimov style.
• If they sentence me to life imprisonment I will just wait them out. Also point out to the judge who sentences me that eventually I will get out since no civilization lasts forever
• And if humanity goes extinct I will just remake humanity from my cache of stored fertilized eggs and artificial wombs that I had like a billion years to get working.
