I don't understand something: if the null pointer was a billion dollar mistake, and has caused pain and system crashes for decades, then why weren't there any attempts to just not implement it in an object-oriented system?

I have one annoying problem with people bashing C/C++ with regard to NULL pointer.
NULL pointer is *C* problem.
C++ has references since forever. Here the problem is programmers not using them. If a *C++* function takes a pointer as a parameter and does not allow it to be nullptr, it's a bug - it should take a reference instead.
std::optional is still newish, so give some slack to pointers still.
CrowdStrike took down Debian and Rocky Linux a few months ago and no one noticed
Nach dem gestrigen IT-#Chaos ist die #Ursache für die weltweiten Abstürze von #Windows-Systemen wohl identifiziert. Schuld ist demnach ein #NullPointer im #Code des #Crowdstrike-Updates. https://winfuture.de/news,144037.html?utm_source=Mastodon&utm_medium=ManualStatus&utm_campaign=SocialMedia

[that feeling when one spends most of the day combing through he internets and code to finally get to a forum thread stating that THIS specific chip on THAT module is not adhering to the ISO standard and thus wont work as expected]
Why I love #Rust:
Every day at work, using #CSharp or #JavaScript, I constantly see potential #NullPointer exceptions littered throughout the code.
The lack of nulls and overall defensive mindset that #Rust enforces leaves your mind free to focus on higher-level solutions.
