From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Not an expert in both the languages but I heard that C developers are trained to use memory smartly, sometimes even reuse a range of allocated memory for completely different purpose to save cycles freeing and reallocating. But for Rust developers, everything is about making sure when one should get the hand away from the memory, and whose memory is allowed to be touched.
Sounds to me like sharing rides that maximise economically but we may have some oops moments sitting on someone's laps vs absolute private rides to make sure no one in your family will be harmed but we have to make sure everyone gets a car only when needed.
It is quite interesting to see how it will work out eventually...
That is honestly a decent analogy. So, on what rides is it ok if something goes wrong and a young family member is killed? Rust says, it is never ok so we won’t let you do it.
To use your analogy though, the issue is the driver feeling quite confident in their skills and rating the risk as low. Then a tire blows on a corner. Or somebody else runs a red light. Or, there is just that one day when an otherwise good driver makes a mistake. History tells us, the risk is higher than the overconfident “good” drivers think it is.
In particular, history shows that 70% of the real world injuries and fatalities come from passengers without seat belts. So, instead of each driver deciding if it is safe, we as a society decide that seat belt use is mandatory because it will prevent those 70% of injuries and fatalities ( without worrying about which individual drivers are responsible )
Rust is the seat belt law that demonstrably saves lives regardless of how safe each individual driver thinks they are. It is a hard transition with many critics but the generation that grows up with seat belts will never go back. Eventually, we will all realize just how crazy it was that they were not always used.
