The fact that a random opponent performs better means that simply inverting the output of a bad strategy (assuming that is even possible, in cases where the output is more complex than binary it should not be) would just give you another bad strategy.

That's the joke, but to be fair, inversion is not a binary concept. Negation is binary, but inversion is more general and has the 2D interpretation of reflecting something across X=Y.

You've actually made an argument for the FDA, not against it. Otherwise patients with cancer would have to decide between thousands of chemical concoctions which will either kill them, let them live, or do nothing, in which case they will still only live or die. Why would there only be one experimental drug on the market if any one is allowed to market to patients independent of efficacy or risk?

CWDM uses lasers too, the reduced wavelength tolerance simply means that the lasers can be uncooled (reducing the power draw) and that chirp (frequency shift during modulation) does not cause interference with neighbouring channels, making them easier to modulate directly. The 'loose' CWDM banding is actually smaller than the bandwidth of typical LEDs.

500% sounds like a deliberate play with numbers, if the default rates were 2% and 10% respectively, I could choose to call that a 500% difference, or more reasonably, an 8% difference.

Close, but dispersion compensation is now very easy to do digitally, and has very little impact on system performance now. As for power, it is actually the opposite, optical systems are ultimately limited in reach by nonlinearity, and so you can not just increase the transmit power like you might do in a wireless system, even if your amplifiers were very linear.

Except YC does not expect to be criticised when YC companies tank, which many eventually do.

And why should they be criticized? That's table stakes for investing: if you want upside you take risk. Does that obligate them to take on losing bets just to appear fair?

Because it means YC itself has a falsifiability problem.

Business (as life) is not science. If you want to find proof of anything go be a scientist, because everything you find elsewhere will just be anecdotal.
