Im a math-let, but im intrigued by Gödel's incompleteness theorem and the fact that there might be correct mathematical statements that cannot be proven. But i also heard that he's often very misunderstood.
Can anyone explain what Gödel really proved and what the consequences of his theorems are?

What it means is very simple to explain in plain language.
Say you have a set of axioms for doing mathematics that includes a system of numbers at least. There are certain things you can prove using these axioms. At each step you could refer back to your axioms and confirm that each one was used correctly in order to verify your proof was correct (or show that it was wrong). You could in principle make this an algorithm.
What Godel showed was that this proof checking procedure will never work if it is applied to itself.
That's also the intuitive idea behind Turing's work, by the way. Which is why you might hear people say Turing also gave a proof of something equivalent to Godel's theorem.

You need to stop being so gullible. Hotz is a good programmer, but not a genius, he's not even above average; he has good verbal intelligence but that's it. His """AI""" startup is just another entrepreneurship scheme, he isn't inventing anything new - who do you think he is, A SCIENTIST? He isn't, he's just 30-something years old guy who's trying to sell you a snake oil because he hasn't achieved anything else in his life and this is his only chance to earn "fuck you" amounts of money, to larp as he's the next Jobs/Musk/Gates for big wigs like Peter Thiel. Read https://www.scaruffi.com/singular/download.pdf to understand why any startup today with "AI" in it's name is guaranteed to be a scam.

What Kaczynski forgot is that leftists will always exist. Leftists are collection of low class men and women - Trannies, sluts, weaklings. You cant defeat inferiority ever you can only offset it. The technology was never problem, the problem are powerhungry leftists who took hold of it and now they are demanding from people to jump as they say.

Between mind and hand is heart and without it the world will always be trash shit full of people who demand power because they are such trash shit goblins that no one even wants to look in their direction.

No. He is well aware of this and emphasized it very strongly.

You are correct on the point about technology though. This is something that people get wrong about Ted most often, placing him as a luddite. The technology is kind of incidental for Ted, his critique is aimed at "the system" itself. Technology serves to enhance the capability of the system, but it's not the technology itself that is problematic.

Ted speaks in terms of left/right dialectics because that is the political reality of the world we live in, but his true thesis is completely agnostic to the particular instantiations that manifest. He doesn't hate leftists or conservatives, he hates anyone that advances and sustains "the system".

a financial education
if you understand how money works and have a good financial plan then an average 50k salary will be enough for you to retire comfortably in 10-20 years.

For example: Your 50k salary allows you to save 20k/year into an investment. Financially literate person knows how to invest at a real rate of return of 10+% allowing him to retire in 10-15 years. Financially unliterate person invests at a real rate of return of 0-5% causing him to work until 65.
Getting a real rate of return of 10% doesn't mean crypto gambling or stocks - it could mean starting a business with guys working for you, online selling, real estate, etc.

When you have hundreds of thousands of dollars invested in a good way this trumps the impact of yearly salary of 100k vs 50k. For example many engineers are wageslaving for 80k, but an uneducated guy can start a roofing business with 5 guys working for him, making a tidy cut on all of their labor.

In evolutionary science this is called a niche. There was less fitness needed to survive as a macroorganism than a microorganism so bacteria began evolving into slugs, lizards, birds, monkeys, etc. We are in the unique situation of steadily increasing the fitness required for our own survival as humans, which means we're either going to get rekt or evolve into a species that doesn't threaten each other with nukes or spam the biosphere with hydrocarbons.

Why would bacteria become extinct?
The idea is that things like sexual reproduction, despite the theoretical disadvantage of diluting genetic contribution to ancestry, is not maladaptive because of countervailing advantages.
There isn't one single solution to successful reproduction. That's why there are millions of different species being selected for entirely different local fitness maxima. And why bacteria themselves are so staggeringly diverse.
Also, some bacteria themselves engage in aggregation behaviour and exchange genetic material (though not through sexual reproduction, of course) in response to resource stress.
