A big concern with transhumanism and immortality is that, like all technology, it'll be very expensive at first, which means only the very rich people will have access to it.
Do you think that the scientists and researchers that initially develop or discover the technology (technology being a prosthetic limb, telomere extending protein, etc. etc.) would also be able to use it on themselves, despite not being rich? Or would they be forced to use it on the wealthy sponsors that they are likely being funded by?
I'm pretty much looking for a way around the "only the rich people will have the options open to them" problem. Although this solution only really solves it for the individual, and doesn't affect everyone who's not some sort of researcher :/

Why does mRNA have introns at all if they're never used for anything? Shouldn't we have evolved so that we only have extrons, and don't have any useless portion of the mRNA that has to be spliced out beforehand?
Edit: as someone pointed out, introns actually has some uses. That being said, there seems to be something that is sometimes referred to as "Junk DNA", which really is useless (by definition). I'll switch my question from "why do we have introns?" to "why do we have junk DNA?"
I can get their derivatives just using algebra and identities, but I'm not sure why there's an absolute value bar around the x in the denominator. These two are the only two of the six inverse trig operators to have an absolute value bar in their derivative.
For reference: https://www.math.brown.edu/utra/trigderivs.html
You can scroll down to the inverse section to see them
You'd see it like this: fl( x )
This denotes the general derivative of f(x). There's a small line (that I can only represent with a lower case l here) which differentiates "f of x" and "f prime of x". Is there a name for that line/symbol? Or is it just a one?
I ask because the notation for the inverse of f of x is: f-l(x). That makes me wonder whether this and lagrange's notation are making use of the same symbol
Since the data is spread over multiple drives, removing one drive screws everything up.
Redundancy is apparently using multiple drives, and if one of them fails you can still use the other ones. But as far as I know, it's not cloning the data to all the drives, it's sharing them across all the drives.
So why does the entire thing not fail when removing one drive, and instead you can safely remove a drive and nothing will happen?
Does the apt package manager automatically install whatever dependencies a package needs upon installing that package? Or do I have to do it myself?
It seems these terms are used interchangably, and as far as I can tell they're defined in the same way. Is there any difference between them?
d/dx is called an operator, but it's always treated as a fraction, ex. d/dx[x2] = dx2 / dx
It makes me wonder whether d/dx is really an operator or not. What exactly is d/dx? I'm totally fine with Lagrange or Newton notation, but d/dx just doesn't make much sense to me.
Are there any scenarios where it's not true?

( (lim as x>c of u(x)) - u(c) ) = lim as x>c of (u(x) - u(c)) ?
The limit of u(x) as x approaches c minus u(c) is equal to the limit of u(x) minux u(c) as x approaches c of
Why is that? Is there some kind of property that states this?
For function f to be differentiable at c, the limit as x approaches c of
( (f(x)-f(c)) / (x-c) )
has to exist. Looking at it graphically this makes sense, but can someone give me an example of a scenario where this limit would not exist?
Sorry for the stupid question, I'm very new to all this stuff (it's only been a bit more than a year since I've had my first job).
Using SimpleTax, I filed my tax return sometime around March this year, and I pretty much just went off whatever was written on the two T4 slips I got (I'd worked two different part time jobs), and I got a check from the government described as "Income Tax Return". I'm guessing the check was the result of whatever I had done on SimpleTax. To be honest, I just entered numbers and clicked stuff, I have no idea what was going on other than that. I'm surprised that SimpleTax can do government related stuff despite being a 3rd party. Can anyone explain that part? Are SimpleTax and other services that do this managed by the government?
Also, I heard that the first time you file a tax return you get some kind of file under your name (and that makes the process simpler in the future). Would I still get that benefit despite having done it through a (seemingly) 3rd party website such as SimpleTax? I don't remember giving SimpleTax much information, I'm not even sure if it asked for my SIN number (although maybe it did and I just forgot), and that's another reason that it seems weird that I was able to get a check just from typing in some numbers: I hardly gave them any information to work with, and it's not like there's only one person with my name and age in Canada.
I only got around 30$ back. I have no idea whether I was supposed to get way more than that, or whether I shouldn't have gotten that much at all. Was that amount appropriate? What exactly does it depend on?
Fundamentally, I'm not really sure why we have tax returns. The money that we get back (or pay) is apparently the difference between how much you pay and how much you owe? But why isn't the amount you pay equal to the amount you owe in the first place?
Even if you don't answer all of the questions, answering even just one would help! Any help whatsoever is appreciated a lot!
Just as a note, I use computing and the biomedical computing plan as the main example in this post
Do employers see your plan in any way? Or do they just see that you graduated with a degree in computing, and have no idea whether you did cogsci or biomedical?
Won't whatever job I get upon graduating from computing pretty much just be a basic computer related job that you could do no matter which plan you followed?
I suppose in the future, after you have more experience, you could get a higher level job which might have something to do with whatever you learned as result of following a plan, but that seems so far after graduation that by that time you'll have forgotten whatever you learned by taking those non-computing courses anyways.
The only way I could see it apply is if you went for grad studies, where you can immediately apply the non-computing stuff you learned and use that to go for more specialized degree in a combination of that subject and computing. But even that point, in Computing's case, is null because most people say COMA is the best option because of the math foundation it gives.
Sorry if this is a stupid question, any answers are appreciated.
I see strength training recommended to older people quite often because it increases bone density and makes them more sturdy. That makes enough sense, but can anyone explain why exactly strength training increases bone density in the first place? Shouldn't it just make the muscle stronger? Why does it affect the bone as well?
There are obviously a huge amount of lessons on Khan Academy for a wide variety of topics that go beyond just math, all the lessons I've seen so far have been narrated and done by Khan himself, not sure if there are other teachers but even if there are, how has Khan made so many tutorials himself? Did he just spend all of his free time making them? It's non-profit right? So he can't just make them for a living...
Just confused as to how one person could have made so many accurate lessons on such a wide variety of topics
I think that, at the root, this is just based on personal philosophies.
Let's just define mind uploading as: somehow uploading all the information in your brain to a computer that can accurately emulate a human brain, thus making a non-biological replica of you (this point in itself can get complicated, ex. how do we deal with sensory deprivation?, but that's an entirely different story).
One point brought up is how we can't scan the brain without destroying it in the process, but let's imagine that we can. If that's the case, there are now two completely individual minds: the one on the computer, and the original biological mind which the computer mind is a copy of.
The original mind cannot experience whatever the computer mind is feeling, and the computer mind cannot experience what the original mind is feeling. It's as simple as that. The original mind will eventually die because it is biological, and the computer mind will (theoretically) be immortal.
Some people argue that since the original mind eventually dies, mind uploading should not count as immortality.
Other people argue that the fact that there exists another identical copy of the original mind means that, in essence, the original mind never dies.
Hopefully you can see that this goes deep into personal philosophies, and there isn't necessarily a correct answer.
That's what I think, I'd love to hear your guys' opinions on the topic.

Firstly, how exactly do things like working at a company during your school year work? Like is working at that company worth some amount of units that you can use to graduate? If not, isn't that time spent at the company better used taking courses which will give you units?
And not to mention exchange programs...although I'm not sure how many opportunities there are for that at Queen's. Are there opportunities to travel overseas to Europe or Asia while also making progress towards your degree? Or is that type of stuff more for graduate studies and research?
TLDR What year do people start doing things other than just courses, if at all?

The derivative of ax where a is positive is simply ax*lna. But if a is negative, that won't work since you can't take the log of a negative number. What is the derivative of ax where a is negative?
I gave it a search but I could only find stuff on the power rule, I'm not quite sure how to word it better. Sorry if this is a stupid question.

tan(5π/4) = 1
sec(5π/4) = -2/√2
Final answer seems to be -2/√2, right? But look at this:
tanx*secx = sinx / cos2 x
sin(5π/4) / cos2(5π/4) = (-√2/2) / (√2/2)2
= (-√2/2) / (1 / 2) = (√2/2)*2 = -√2
Is the correct answer -2/√2 or just √2 ? What am I missing?
Any help is appreciated.
