It's very possible we never break the factoring problem. Since we have no properly unified theory of physics (e.g., one that models the observer in QFT), there are outstanding unkn…

We have no good evidence or accepted model for how life started, besides "randomness" in a primordial soup, which is as good as "no idea". As such, it seems like a reasonable assum…

Only technology can save us from global warming and only private enterprises like Tesla and others can develop and - more importantly - cheaply scale that technology. There are bil…

Yes, you're right. I should have said, there's no better choice of symbols that will remove the huge set of prerequisites you need to first understand. There isn't as large of a to…

I'm both a programmer and a mathematician. Mathematics is written in English (or another human language) plus added symbols. The symbols are what we refer to as the notation. It's …

The primary transmission route in inhalation in close proximity to an infected person. Yes, it can persist on surfaces, but this hand-washing meme is mostly a result of (1) it cost…

What does hardware 1 and AP1 have to do with the latest hardware and autopilot?

The system is absolutely AI based today. There is no hardcoding like this. Hardware 3 in Tesla cars is an ASIC meant to run neural nets ( https://en.wikipedia.org/wiki/Tesla_Autopi…

Future profitability is how equities are priced. Ford is expected to not be (very) profitable while Tesla is. Number of units sold is irrelevant.

The idea that the ascent of humanity into the stars and the potentially incredible understanding of the universe we could gain would be stopped by 2019 regulations because amateur …

Leetcode premium doesn't mean you'll see the problem. I suspect the probability of that is low, given these problems are constantly changing (there's a banned problem list at Googl…

I 100% would be able to solve this problem without seeing it before. Yes, this is because I've practiced a lot of algorithm problems (and I enjoy them, frankly). Yes, this is hacka…

Some analyst at Morgan Stanley made up that $100B number. It has ZERO meaning and no one should take it seriously. The market cap of a company is what investors are willing to pay …

So what? Products improve. This one will too. Imagine seeing an ad on Youtube and immediately being able to play the game on your chromebook. I don't know that's what is going to h…

As someone concerned about climate change and very bullish on alternative energy, I still think this is a slippery slope. Google shouldn't choose who can use its services based on …

VW has $44b in cash and $160b in debt.

Tesla has over $5Bn in cash and positive operating cash flow. You can argue about $TSLA the equity's valuation, but whether it survives long-term is no more questionable than wheth…

There is absolutely no way beef spikes insulin as much as rice does. Beef has zero carbohydrates and while some protein does convert to glucose, it is a slow process and thus the i…

Agreed. I don't want to see hosts challenging their guests' ideas. I appreciate Sean Carrol's physics podcasts for exactly the same reason: he doesn't always agree with his guest's…

Why shouldn't we hear what nationalists have to say? Who gets to decide what is a conspiracy theory? They're not all as simply false as flat earth. Keto in the low-fat 90s would ha…

Hacker News has become tribal and politicized, much like many other parts of the internet.

>>If we believed that Amazon is actually creating 25,000 NEW jobs, as well as jobs that otherwise would not exist, it seems pretty reasonable to say that the state and city come ou…

I don't think the hedonic treadmill or that link has anything to do with your statement "the average person spends almost exactly as they make as income rises." The hedonic treadmi…
