Curing disease is not worth it if the price is the permanent deprecation of most human beings' existence.Their words
As someone coming from a biology background, who considers “curing disease” as a very noble mission, I still believe that the vague promise of “curing disease” is fundamentally not worth it if it comes with a form of permanent deprecation of most humans’ existence.

Humanity is not good enough at molecular biology to make drugs that restore vision or hearing or stop Parkinson's.Their words
People have spent huge amounts of time and money looking for drugs to restore vision or to restore hearing or to stop Parkinson's or to to help paralyzed people move again. Understanding the like the biology and the molecular detail required to make a drug has been very difficult. Humanity just isn't that good at that, to be totally honest.

Drug companies pile onto the same few already-validated targets, so far less of biology gets explored than could be.Their words
In biomedicine we have a problem called target herding: most companies chase the same biological targets because they are de-risked, which means we explore far less of the biological space than we could.

The patent system then further disincentivizes companies from taking target risk, because it rewards novel chemical matter, not novel biology.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.
About the English under a post
Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
