I want to be immortal /sci/. What are the chances of it being made possible during our lifetimes? What can I do to increase that chance?

There is zero chance it will happen in our lifetime, and also it would require genetic manipulation of your fetus. You will die.

Second to third line is wrong. We do not generally have root(ab) = root(a)*root(b) if root a or b is complex.
>>
>>8591463
[math]\displaystyle \sqrt[n]{ab} = \sqrt[n]{a} \sqrt[n]{b}[/math] only works for positive real numbers.

Can anyone show me how this is true?

[math]\sum_{i=1}^n (x_i-\mu)^T \Sigma^{-1}(x_i-\mu) = (\bar{x}-\mu)^T(n\Sigma )^{-1} (\bar{x}-\mu)[/math]

You can use the fact that [math]\sum_{i=1}^n x_i = n \bar{x}[/math]

Allow for a suspension of disbelief before answering this next question.

Say AI can do your job way better than you, faster, more creative etc. Now say that we have enough surplus to provide you with a 300k per year check just for existing.

What will you do?

Read more books.
Go back to school.
Hire a chef (robot).
Hire someone to shock me every time I go back on /sci/.

>>8595701
Yeah but why would anyone want that fucking job if everyone is making 300k bottom line?

Also be more creative with your answers. Really think about what life will be like after jobs are abolished and the human no longer has any real purpose.

Would you go on a killing spree?
Would you build a castle and wage war?

No. There is no consistent theory in physics that allows for time travel back in time.

How does a person actually become immortal, and what is the best someone can do now to extend your life long enough to achieve revolutionary technologies (OTHER THAN diet and exercise, because everyone already knows that and it doesn't actually extend life, just prevents you from dying early)?

Also, let's dispatch with the "hurr upload mind into robot" shit too. This isn't about that. Nor will it be considered. Go play p zombie elsewhere.

>How does a person actually become immortal
The most likely avenue, to me, involves the ability to regrow human bodies and minds from scratch, with the brain contents of an earlier stored copy; an ability to create these copies, with a nondestructive brain scan of some sort; and regular backups.

>and what is the best someone can do now to extend your life long enough to achieve revolutionary technologies
Cryonics, I'd think.

>Also, let's dispatch with the "hurr upload mind into robot" shit too.
Why? Is there a real difference between improving your body in conservative ways, and just replacing it with an all-round better-engineered thing?
>>
>>8595181
>with the brain contents of an earlier stored copy
Ah, I see you're retarded, yet clever. You decided to avoid the "upload muh brain into a robit" argument by simply going with "upload muh brain into a clone". A for effort, F for IQ.

>and just replacing it with an all-round better-engineered thing?
You mean with someone else? Yeah, it's called reproducing. That's not immortality.
>>
>>8595186
Oh, I'm sorry. I mistook this for a thread where OP might be interested in actually discussing possibilities. But it turns out to be just another thread to bait for, and then shit on, ideas that OP doesn't like.

I wish your shitposting thread the best of luck, OP.

Do a distance learning course in Open University perhaps.

Yeah UK. Don't want to pay for more "education", will self learn but don't know where to start. Any suggestions?
