I wonder how many false positives there were. Typically this types of static analysis tools come up with a ton of potential bugs, but only a few of them are actual bugs.

Sora was losing 15M a day and it was running at least 3 months, so that's a total 1.3 Billion. That's a pretty expensive experiment. It sounds like a company with lots of VC to burn and no discipline. Even Jensen Huang accused them of lack of discipline in business approach.

also they need to pay back that in one year, so if OpenAI don't IPO this year they are screwed

You need to be careful, because this doesn't work if the value is negative. A

OpenAI actually burnt $12B in just one quarter (not for the entire year as he claims)

c++ 03 was a lot easier.

For instance, if you want to avoid unnecessary copy operations when returning a string, just return it in variable that you pass by reference (eg. void doSomething(string& str);) likewise avoid the vector class making unnecessary copies, simply by creating the objects on the heap and use a vector of pointers instead of values. It's a bit more ugly, but it works, and you don't need to read a 24 page blog to understand all the corner cases where it can go wrong. modern c++ is all about syntactic suger.

Tanks don't really make any sense. MBTs are designed to fight other MBTs. Out of the thousands of tanks that have been taken out in Ukraine, 99.999% has been by drones, artillary or ATMs. You can count the tank versus tank battles on the fingers of your hand. Wouldn't make more sense to evenly distribute the weight of the armour, so the back and top are reasonably armoured, rather than have foot thick armour in the front to stop rounds from other MBTs - a scenario which literally never happens.

They don't want to close the loopholes, because the loopholes give American companies an advantage over foreign companies.

I'm surprise people say it had gory videos. I've being watching Liveleak for the last year. There were hardly any videos with violence and gore. The videos could be classified into 4 categories: traffic accidents, drunk/stoned people doing stuff, police cam recordings, industrial accidents (cranes, ships crashing etc.)

I would not say that at all. The biggest disadvantage of Vulkan is that it doesn't support old GPUs
