 - In 3rd world [pigeons carrying SD cards](ip_over_pigeon.md) are still much faster and reliable way of transferring data than [internet service providers](isp.md)? This also avoids [censorship](censorship.md).
 - That [compiler bomb](compiler_bomb.md) is a very short source code that makes the language compiler produce gigantic executable?
 - That there is a light bulb in California that has been turned on since 1901 and as of writing this is still working? This shows that [old](old.md) things are better than those manufactured under more advanced [capitalism](capitalism.md) which pushes for more [consumerism](consumerism.md) and applies [artificial obsolescence](artificial_obscolescence.md). Many sowing machines made mode than 100 years ago still function perfectly fine as well as many other types of machines; anything created nowadays shouldn't be expected to last longer than 3 years.
+- That there exist [numbers](number.md) that are not [computable](computability.md) or are otherwise [unknowable](knowability.md)? See e.g. Chaitin's constant.
 - That throughout [history](history.md) one of the most common patterns is appearance of new lucrative technology or trend which is labeled safe by [science](soyence.md), then officially recommended, promoted, adopted by the industry and heavily utilized for many years to decades before being found harmful, which is almost always greatly delayed by the industry trying to hide this fact? This was the case e.g. with [asbestos](asbestos.md), [freons](freon.md) (responsible for ozone layer depletion), [x rays](x_ray.md), radioactive paint (see *radium girls*), some food preservatives, [plastics](plastic.md), smoking and great many prescription drugs among which used to be even cocaine. Yet when you question safety of a new lucrative invention, such as [5G](5g.md), antidepressants or some quickly developed [vaccines](vax.md), you are labeled insane.
