This is irrational. The risk of waiting for a few hours to test in a small environment before deploying a 0-day fix is marginal. If we assume the AV companies already spent their sweet time testing, surely most of the world can wait a few more hours on top of that.
Given this incident, it should be clear the downsides of deploying immediately at a global scale outweigh the benefits. The damage this incident caused might even be more than all the ransomware attacks combined. How long to take to do extra testing will depend on the specific organization, but I hope nobody will allow CrowdStrike trying to unilaterally impose a standard again.
Pairwise independence is to give the algorithm stronger guarantees and let it work with a simple hash function like ax+b, otherwise probably most existing algorithms can be simplified in the same way. The most similar algorithm is BJKST, which is almost identical except for specifyimg the sampling mechanism to require less randomness.
To someone who worked on this type of thing before, it's like seeing people familar with LLMs say "oh yet another X-billion parameter model on github doing more or less the same".
Fortunately it doesn't take that much to get top talent, because so many other companies underpay. Jane Street only has to pay out a small fraction of their PnL and doesn't even need to have a non-compete.
But before you complain about that, R&D paid to universities also include overhead for the universities, and it is quite significant. In US it is over 50%. The universities partly act like investors in this way, the administration invest money (e.g. start-up grants, some professor salary) into research groups and expect them to bring external grants, and the overhead partially pays for that.
Depending on what you want to measure, you need to include the cost of people and resources involved in the production of the thing you want, and not just the marginal unit cost of the thing. It may not be easy to draw the line, but you have roughly two choices:
1. Deduct a reasonable percentage from both university grants and M&A
2. Accept that without profit, people would not have funded certain research (which carries risks and requires selection), so you include those as costs of doing business in your assessment
Another way to think about it is that the money you spend on research itself containts other people's profits too. If you buy equipment, the equipment company makes a profit. Staff has savings. The govt always takes a cut. It's profit all the way down.
Exchanges do provide very limited special conditional execution instructions such as peg orders or stop orders, but it seems like a hard problem for them to support anything more sophisticated and general.
It's much easier to write better essays when you care a lot about something, really want to make it convincing and spend effort polishing your technique based on actual reader feedback. Even the "form" taught at school doesn't really matter because different audiences and topics require different arguments and require you to focus on different details, so the best kinds of essays often look nothing like say full score GRE writing test essays.
Most people who claim to be polymaths are dilettantes. Even if they are really smart. People who claim they're polymaths don't have the humility to recognize it's very difficult to be at the forefront of two disciplines. A dilettante wouldn't know this because they don't know the amount of effort and learning it takes to be a true expert.
A true expert spends a lot of time on a subject and may on the surface may appear to have no more knowledge than someone who just reads and follows their papers for less than half the overall effort. This is because much of extra work is spent on trying different ideas and learning for producing the next good idea, or trying to apply it effectively in various contexts, rather than just learning other's good ideas for the sake of it.
Whether the expert is more valuable in dollar terms or potential impact than the dilettante or a humble generalist is another question. People can indeed be good at wearing multiple hats and create value. But I think someone like that should recognize that they are trading depth for breadth and not claim they are better than others at everything they learn.
The next thing to explain the discrepancy between Nvidia's valuation and OpenAI's would be that Nvidia's monopoly position effective eats into the profits of the AI startups for the foreseeable future. Had OpenAI already been profitable, its valuation would have exceeded 86B.
With that said, I do believe Nvidia is overvalued - if it triples profit its PE ratio would still be 30 (i.e. 30 years to return on investment), while there's a fairly good chance someone would catch up to them in 10-20 years.
