While genetic research has huge potential in early diagnoses, and possible prevention, of illnesses caused by genetic defects, the statement that one can determine (general) intelligence of a potential offspring by checking embryos seems nonsensical from the get go.

First of all would be the definition of (general) intelligence. What exactly is it? Even when assuming that an IQ test cannot be cheated, the concept of reflecting one’s general problem solving skills by a number makes little sense. Can we really say that a savant that heavily struggles with everything but in one field has the same intelligence as someone that is completely standard in any way when both have the same IQ score? I would say not, as the former would need much more support than the latter.

Furthermore, often points concerning something related to eugenics ignore the nature vs nurture debate. How much of our skills are dependent on our environment? To what extent can we say that our minds have a limit on how intelligent we are? It’s hard to say, as there isn’t much research about it, and experiments on that topic are often inhumane, historically speaking. So we need to keep this lack of knowledge in mind when talking about topics like eugenics.

Alternatively you can also use aluminium. Snails have a natural allergy to aluminium due to a reaction happening between the metal and their slime. Therefore they will avoid aluminium at all cost.

As well as the proportions being flipped, resulting in the now iconic look. IIRC it was supposed to be a pig initially.

I think the main problem is that people try to shoehorn OOP mechanics into everything, leading to code that is hard to understand. Not to mention that this is basically encouraged by companies as well, to look “futuristic”. A great example of this approach going horribly wrong is FizzBuzz Enterprise Edition.

OOP can be great to abstract complex concepts into a more human readable format, especially when it comes to states. But overall it should be used rarely, as it creates a giant code overhead, and only as far as actually needed.
