Please correct me then. After a bank robbery, the notes' serials get marked in a database and when they go out of rotation they are destroyed, the bank gets a new bag of notes and the FDIC assures that whatever happens your money is recovered - through another bank if necessary.

The entire economy is not backed by bullion in a bank's vault, 'losses' in the digital side are simply recovered by rolling back statements. If your account gets hacked and the money is transferred within the country, it can simply be recovered by transferring the money back because all the accounts fall under the same 'governance', even internationally there are some agreements for returning stolen money. If a 'mule' is used, the mule's balance is going to go negative and thus someone, somewhere will be indebted to the banks (whether it is the victim, a mule, the insurance company or the criminal). When insurance companies have to recover the money, they will either get it from the feds or lend the money somewhere (depending on the type of insurance and your jurisdiction - eg. in Europe, a lot of the insurance pools are backed by the government which makes the actual payments)

Cryptocurrency cannot be recovered or re-issued like bank notes can. You cannot have a negative amount of cryptocurrency because it is decentralized and supposedly anonymous. There is no governing agency or international agreement on recovering stolen cryptocurrency, no agency can just issue more currency and subsequently recover it at a later time. There is also a limited supply of them and creating them is costly so it is not feasible to simply have a stash somewhere just for insurance purposes because you would only accelerate the devaluation and instability of the system (if someone holds like 1/3 of a cryptocurrency they can technically 'cheat' the entire system)

The insurance is the least of their problems. For a good fee anything is insurable. The problem lies in the replacement. Banks/Feds/Insurance when losing money just replace the number in their databases or print the money, no insurance company nor bank nor the Feds actually has a reserve of cash to cover all their accounts in case of a massive hack that empties all their accounts. Not as easily done with cryptocurrency, once it is gone you can only replace it with more cryptocurrency. So you actually need to stash or be able to lend the insured amount instead of just relying on someone to bail you out with fake money.

So-called readable and simple code is usually the least powerful because there is more time spent on it's semantics than what it actually has to do. Sometimes it gets so simplified that more complex operation require loads of customization to make something perform well (eg. by building additional C libraries -> see Python or Ruby) so it just is simpler to just do it well the first time around.

Bad credit scores usually means you're bad at managing money and thus more likely to steal and/or be less productive.

You don't need debt to have a good credit score. My credit score is perfect and I barely have had debt (besides a mortgage and a car payment). A good credit score means you are on time with any payments and not going into sudden debt (eg. overdrawing your accounts).

You just have to live within your means, I have gotten heavy hits to my income but I didn't keep spending the same amount of money, therefore I have a good credit score.

Regardless, HR drones shouldn't be checking people's credit scores, if I were in the hiring process and got alerted that the company pulled my credit score, I'd sever my ties with them anyway as I do with any company that has pulled my credit score without permission so far.

systemd is fine if you don't want to fiddle with anything. It is great for the current cloud/virtualization hype because it doesn't use arcane text files which are different for each daemon but rather everything is uniformly structured so you can spin up entirely self-automated datacenters with a few presses of a button in a web interface. If you want to change your hostname, you issue a command and everything that supports systemd now has your new hostname.

However if it breaks, it is bad. Things are a mess for humans to read or change, it seems to be entirely built to be used in purpose-built GUI's and web interfaces. It has or will become the registry of Linux. If you want to use something that's not systemd-aware you're either stuck encapsulating old scripts in systemd scripts or building an entire infrastructure of dependencies and requirements around the daemon.

The thing is that a quality laptop (which Apple is one of) will continue to work at full load. As the OP stated, "others", especially custom builds have random issues ranging from shutdown/reboots, severe throttling or even hardware damage if you keep them at that load for a while. There are few laptop builders, even big names, that take care in what they put together.

Dell is one of those that will mash together a laptop, sometimes even with a full-blown desktop processor and whatever else you can specify without actually knowing it will work. IBM used to be a good name, Lenovo not so much anymore, Fujitsu-Siemens is/was a good name a few years ago at least but haven't had an experience in years, Asus is decent but their cheaper models are hit-and-miss. HP, Toshiba, Acer, ... stay away from those. There are/were some companies that will custom-engineer a model and test configurations for you but you will pay a hefty premium.

There exists no PC that costs $300 that will match up to a $2k Mac. Even if you plunk down $700 for a Mac Mini with AppleCare, it will be hard to find a similar machine with a similar service contract (think Dell Gold Service Contract).

Apple will come to you within 24h or ship you a new machine overnight but even after the warranty expires you can still call them and they will answer you. I have dealt with Dell, HP and Lenovo, it doesn't even come close.

I don't know what you're doing with your laptops to cause such issues, are you working in the Sahara?

There are plenty of laptops out there but if you want a somewhat decent one, go for a Macbook Pro. Sure they're a bit more expensive (although not as expensive per feature as Dell) but I haven't had issues with them doing serious dev, cross-compilation and heavy computation (MATLAB, Python etc) work that can take 100% of all cores for days on end.

If you need desktop performance, get a desktop or get the building/compiling to work on your compile farm. A laptop with a desktop processor will overheat/melt/break and there are plenty of builders that will mash together whatever you specify without any real testing. And "boost" speeds are just that, they're only there to boost the occasional spike, physics will take over at some point. For the work you describe (prime calculations) you'll get much more efficiency out of a decent set of servers and have your coders check in their work after which a bot will automatically attempt compilation.

Depends on what you declare as modern. I have a Sun UltraSPARC box from the mid-90's which is still used to cross-compile things. Some things just stick around especially in government and research but also in established businesses, things are kept alive for decades because there is no funding to replace it and for most projects the people that maintain it are cheaper than establishing a new project.

This is mainly due to the inbreeding and subsequent incompetence on behalf of the people in charge of finance and IT but also incompetence on behalf of the other managerial staff to recognize that those people in charge are incompetent.

To this day there are very few projects in large organizations like governments, schools and old businesses that include line items for security, maintenance and replacement. Most managerial types still think that solutions are a one-time cost and that, like machinery, it will run fine as long as a mechanic puts some oil and parts in it and when they need something faster or better, they can simply sell or reuse the old 'machine' and recoup 50-80% of the investment in the 'faster' machine.
