Do we agree with W. Tait's thesis that finitistic reasoning = PRA?
https://www.jstor.org/stable/2026089?seq=1
>and the finitist has no concept of a function. He can only see each particular instance as valid. Indeed, if it were otherwise, the function that assigns to the Godel number of each closed term of type N the value of that term and assigns 0 to each number that is not the Godel number of such a term would be finitist. Since this function is not primitive recursive, our thesis would be contradicted.
As a finitist, it seems to me perfectly possible to speak of functions as methods for taking an object of type A and producing an object of type B. Why would this not be finitist?

What are the implications of Quantum Randomness being truly random?

Doesn't that mean we have concrete proof that science can't understand everything? Science has no conceivable way to ever predict a quantum random outcome... therefore... it is solid proof that this universe exists in a way that is beyond scientific grasp... science can never truly understand our world.

It's not sufficient that you can predict the "odds" or likelihood of quantum random scenarios, the issue is that the precise outcomes are not deterministic, which means that there are real phenomena that are beyond scientific reach.

"Science" has never suggested it knows everything. The whole idea of science is that it has theories about how "everything" works.

But yes, quantum randomness is a gigantic gap in logic. My guess is that there is an answer, but it wont be found in 100-1000 years or so, and that the person who figures it out is the "next Einstein". We're living in the era if of "quantum eather"

For example, vacuum fluctuations, how can the energy be predicted?

If it can't possibly be predicted, then it violates the same logic which justifies other areas of science and math.

If it was truly random, we would only see noise. Us, being able to see the world, implies that there is a hidden system.

Stagnation isn't a comfortable lead. Stagnation is akin to sacrificing the future generation to avoid investing this generation. Stagnation is reaping the rewards of last decades and celebrating it as tomorrow's success.
If US fails to spool up their innovation machine, there's no expectation of any comfort for future. Hoping that China fails or stagnated like US is a wishful hope. Future belongs to those who seize their moment and not those who take things for granted

It is a comfortable lead, just not for the future generations. It's quite clear you actually understand the point, but what you're saying is really tangential rather than counter to anything I said.
The leadership will not feel any consequences for their bad policies. The US continues being quite unthreatened by any competitor, and only when there is an actual, concrete threat, are societies required to select for competence in leadership. Iraq and Afghanistan were terrible decisions, but it just didn't matter, because the US was never going to face a threat to either its existence or its position as world leader because of them, and any other consequences were so far down the line, there was no reason for the Bush administration to care. A society which is already in a dominant position doesn't feel such an urgent need to improve itself and future generations, because the relative cost for not doing so is far less perceptible.
There isn't any coherent argument against this. It's just what societies do.

It's not this. It's lack of family leads to lack of desire to invest in society leads to lack of responsibility leads to living only for yourself and your enjoyment.
If you want to blame something, blame women not wanting to marry the average male while everyone is still young and has youthful vigor and room for paternal development.

I am in my second year, but I plan to study mathematics and get a master's degree in mathematics. That way, changing my major (my university does not allow me to change my major if the subject is very different)

What would be my IQ?
