34 Hard Truths You Should Know Before Becoming “Successful” @BenjaminPHardy #Thread
1. It’s Never As Good As You Think It Will Be.

Until you appreciate what you currently have, more won’t make your life better.
2. It’s Never As Bad As You Think It Will Be
The problem with dread & fear is that it holds people back from taking on big challenges. What you will find — no matter how big or small the challenge — is that u will adapt to it.When u consciously adapt to enormous stress, u evolve.

What #AI lacks, humans can fill in.
What humans lack, who will fill in.

Dual standards of our society and human thinking. #Ethics, #fairness and other values are regulated for AI but same values for humans are not regulated.

Time to do introspection.
If humans are unable to grasp the ethics, morale and fairness values due to deep diversity of humanity, how can we ensure ethical frameworks created for #AI will be universal.
Humans have failed to uphold the values of #ethic across history and geography. Humans have used the technology to gain control and become superior. The weaponisation of #ai is inevitable. We have seen parallel cases from field of #biotech and specific case of #crispr

In God we trust,
In #machine we believe,
In #data we live,

We are the next-generation human being.

Sadly we don't trust humans, we don't believe in them and we have almost stopped living.
Religion, folklore, mythology and history agrees on one interesting statement.

Humans were created in image of God.

Aren't we repeating the same thing with #AI? Aren't we creating AI in image of ourself?
Don't believe, look around see with what it is compared.
Sufficiently advanced science is indistinguishable from magic.

Same way, sufficiently advanced #AI is indistinguishable from #god.

Another set of questions are related to algorithms bias, fairness, and responsibilities.
#AI #Algorithms #bias #fair
#antitrusthearing
Security and safety of consumer, product, partners and Algorithm is next set of questions. Again no satisfactory answers.
#Algorithms #AI #security
#antitrusthearing very interesting question, how will you ensure that biases of your employees are getting in to the algorithm?
In fact research has proven that algorithms are learning not from the data but the way data was labelled and annotated. #ai #bias
