Ofcourse they too are only men, and not innfalible to corruption, which will be payed for if not repented when judgement is due. One can also observe that most of the sins written in the bible, are considered to be sins by even disconected tribal peoples, whom often arbitrarily punish the offenders without just due. Even simple logic tells us that for morals to exist, there has to be a judge, and this judge is the one of the bible. For something to have meaning, it would also imply that it must exist, and that is the same with god and morality.

SOON TWO biotechnology firms will begin to offer couples undergoing in vitro fertilisation (IVF) the chance to screen embryos before they are implanted in the mother’s womb. This kind of preimplantation genetic diagnosis has, for nearly 30 years, been widely used to test for chromosomal abnormalities or specific genetic disorders that affect only a single gene, such as cystic fibrosis. MyOme, based in Menlo Park, California, and launching in 2019, and Genomic Prediction, based in North Brunswick, New Jersey, have something more revolutionary in mind.

The two companies hope to reconstruct the important parts of an embryo’s genome using just a few cells from a biopsy and genetic sequences of both parents. With the resulting genomic data in hand, the firms can then, in theory, calculate the risk of the embryo developing a wide range of different diseases in later life. Crucially, the ailments in question may be extraordinarily complicated, involving thousands of genetic variants (common mutations) in different parts of the genome.

Other outlets posting the same story:
https://www.newscientist.com/article/mg24032041-900-exclusive-a-new-test-can-predict-ivf-embryos-risk-of-having-a-low-iq/
>The idea of using such tests to select embryos predicted to have high intelligence is “repugnant, but technologically feasible”, says geneticist Peter Visscher at the University of Queensland, Australia.

https://www.theguardian.com/commentisfree/2018/nov/19/designer-babies-ethical-genetic-selection-intelligence
>So the science behind embryo IQ testing is still shaky. But before we get too indignant about the horrors of designer babies, bear in mind that already we permit, even in the UK, prenatal screening for Down’s syndrome, a disability that produces low to moderate intellectual disability. It’s not easy to make a moral or philosophical case that the screening offered by Genomic Prediction for low IQ is any different. There may be more uncertainty but, given not all IVF embryos will be implanted anyway, can we object to tipping the scales? And how can we condone efforts to improve your child’s intelligence after birth but not before?

To me it seems the lefties familiar with the science are coming around to the idea and are wondering how to implement it within their own ideology. It's not science fiction. They'll throw some chaff in the air but they can't deny the technology exists and works, only that it might have complications or is unethical.
>>
>>10156731
> repugnant
Will these people fuck off. What's repugnant is adoration of sickness such that you would condemn all humans to suffer with it.

I have vicious crohns and i would have been glad if another embryo had been selected free of it. Sure 'I' wouldn't have been born but that thinking is redundant, there's potential you's lost every decision you make.

Most modern scientist don't just don't delve deeply in metaphysical stuff, just socially follow what's high status in their time (in the current year, being a liberal atheist).

You are transported into the realm where an all knowing and omnipotent being resides. You can ask this being any question but it will only respond with either

desu if I were the being, I'd snip your head off for this question
>>
>>10156908

If the being answers that some human does know then this contradicts the known answer that no humans know the answer. Thus the being must answer that no humans know. But since it is known that the being must answer that way then humans know the answer to the question, contradicting the answer that no humans know the answer.

As someone with a 77 IQ (I took the official test) do you think I should take CS? I was planning to study some type of social science because of my low IQ but I've heard so many stories online about brainlets doing well in CS... Wat do /sci/?

Med is prettty much memorization, right? Read something and understand how it works. Done.
Engineering, however, is read it, understand it, and then practice which require more thought.
>>
>>10157322
>understanding how multiple organ systems is not something you can "memorize"
so how do you understand it...? engineering has numerical substance and solving problems with the things like calculus and linear algebra, how do you solve a problem
I know osteology book has no mathematical formula
...you don't use phylogenetics or molecular biological method to pass the pharmacology exam, if it is not a memorize fight then what is it?

What is it that makes engineering such a joke on here? I study at KTH and pretty much all my professors are people who have studied engineering physics, if you go physics bsc + master you are pretty much considered retarded as engineering physics is superior in every way.

Medicine requires more time than engineering. You won't be able to cover the material more than like 2-3 times unless your reading speed is superhuman.
Engineering on the other hand. It's more practical. You can rely on your natural affinity for equations, math and creativity

blah, blah, complex organ systems, blah, blah biochemical pathways. Seriously i understand that medicine is difficult because it requires lot's of memorization, but seriously memorization is different than intelligence, you can memorize tons of facts, and it doesn't make you a smart.Being smart is about understanding things a deeper level and being able to solve complex problems like the quantum physics equations required by the engineers who design particle accelerators i bet 90% of doctors would never be able to understand the material required to design a particle accelerator, in comparison doctors are actually just NPC's, to these engineer's, engineering is a completely different kind of intelligence it requires less rote memorization but much more understanding and intelligence

Any biotech anons here to discuss the current state of this tech? I see progress has been made at drastically cutting down the number of off-targets and magnets can be used to direct it to specific tissues - so why is it not everywhere yet?

depends on your editing efficiency as to how well that could work in practice, off-target effects notwithstanding
