With an algorithmic feed, it's probably easier to get biased into thinking that what is shown to you is representative of trends in the rest of the world. (even if we are conscious of the information bubble, our brain probably makes this construction).
My take on this is that in a small company, the individual with his morals and values can still have an impact on the behaviour of a company. Above a certain size, when the company is public, the individual has less impact on the company, and there is an emergent behaviour that is only driven by the incentive to "enhance shareholder value", and all moral values that the company could follow, and that come from individuals in the company, disappears.
A company's social role is to provide jobs and goods for the society to work well. But this is not aligned with the survival incentive of the company, to "enhance shareholder value", which becomes it's only role.
It seems to me that the direction of the thinking goes the other way: in one, you think of a friend and contact him, in the other, you think of yourself, show yourself to the world and people send you likes.
When I thought of this, it seemed to me that social media is often some sort of "narcissistic exposure of oneself" and encourages this type of behaviour from me and I didn't like it. This plus the fact that I didn't like Facebook's behaviour with it's user's data made me delete my account, and I didn't miss it since. If I think of friends, I have other means of contacting them that have a more personal feel.
There are interesting videos on the subject on Robert Miles channel on AI safety: https://www.youtube.com/channel/UCLB7AzTwc6VFZrBsO2ucBMg
Other than sympy, a technique for formal proof might help.
One of my buddies showed me this talk from Leslie Lamport that I found interesting [1], albeit in french. I think this one [2] is an english version. And the paper behind is here [3], linked from Lamport's website [4].
Lamport makes a structured way to write proof so that all details can be written down. It seemed to me that a lot of knowledge and steps stay implicit in proofs. So if you're not familiar with the subject, you easily get lost.
