Over 10 years of experience. Personality: Don’t bother me with web3, imaginary currencies, quantum “computers” and other nonsense. I am familiar with actual quantitative finance and cryptography, not imaginary stuff you sell. If ur project is funded with imaginary money (e.g. most of USD, digital tokens, “crypto”) - u cannot really spend that money, since they not backed up by natural resources, you waste air you breathe and food you eat believing in religions socialisms corporate etc. Don’t bother me with HoTT nonsense. univalence is an idiotic idea - if everything is identical to everything, it is simply desensitization from reality, it is not what mathematics are for. You turning FP into a joke with imaginary type-safety. USA ship GO F URSELF together with ur slavic garbage u imported, enjoy going hitler on them and Jews with their imaginary money just because u could not leave them to die in isolation, but still have no resources to keep Jewish fantasies and religions; socialism/communism is just pathological infinite loop wasting natural resources, capitalism cannot function when u delegate financial decisions to idiots and pathological liers. the worst price to pay for u is to realize nature does not care, u wasted ur own energy on bs beliefs. EU - start making up for your bs or the same fate will await you, stop acting arrogant with Ukrainians, I did not even grow up in there, but even as ethnic Ukrainian and language speaker I can understand how annoying ur behavior is, eg Holland or Belgium, but also how stupid they are not telling you explicitly. Or not realizing that their money are wasted by naive idiots in FED as well as Israelis rebuilding imaginary alien state. Ukrainian talents and potential are wasted in a war against idiotic morons, grown on American money FED keeps giving them - USA and Israel suppose to wipe ru out, it was American mistake to invest to it (as well as each wipe out each other together with Arabs, Indians, Chinese and other overgrown nations). Ukrainians did not print the imaginary nonsense money, Jews did. We did not build imaginary states, Jews did. We did not cause overpopulation, Jews did - bringing imaginary stuff en-masse requires resources this planet simply does not have (then something like nazi’s arises after Jews fail local economies, e.g. German economy pre-WW1, DeutscheBank). They are not suppose to delegate fixing their own mistakes to Ukraine, and you Ukrainians are not suppose to adapt their idiotic credit system, it’s hidden socialism/communism in there. Every country in the world without exception became poor after believing in Jewish ideas, even pro-capitalist “Human Action” is a garbage reading. Send Jews where they belong to: comedy and television, and pay them as much as that “work” actually worth. And keep reality checks on that - fantasy is fantasy. Upwork. Enjoy re-verifying my id all you want. Crazy Jews at Mossad literally believe they gave me Ukrainian passport coz they cannot make sense of data they illegally collected . That is the value of government-issued ids, as well as most of ur threats and games. I literally proposed PoW (hash cash) as an alternative to ur selfies and other annoying non-sense (see mega-peers). As soon as u run out of imaginary money, someone might just try that.
