On: A physicist who bets that gravity can’t be quantized

[astrange]

That would be very fine indeed since the CMB doesn't eg seem to be pixelated and we don't observe numeric instability anywhere.

[naasking → astrange]

I wouldn't even assume that discrete theories must have a resolution that can be detected.

[astrange → naasking]

Any amount of quantization should have very noticeable indirect effects somewhere. Try implementing game physics and you'll see it.
