Artificial meat and food may be among our best tools to solve the problems of animal cruelty, feeding a growing population, and (in part) global warming. What do vegans and vegetarians think? In favour of cruelty-free lab-grown meat, or against it by principle?


I often say that I am not a fan of ‘-isms’. Not even those supporting the causes I care for, such as transhumanism. I sympathise with some ‘-isms’ (again, such as transhumanism), but I never consider myself a ‘something-ist’. The reason is that, generally, ‘-isms’ have two problems. The first problem is that they almost always support at least some ideas, or make certain claims, which I disagree with or find too fanciful (certain acceptations of ‘mind uploading’ come to mind, but that’s a story for another post). The second problem is that, if you say you’re a something-ist, people will almost surely assume that you endorse, or believe in, some ideas that are really not your thing, merely because such ideas are either an integral part of the relevant something-ism, or are what people think something-ism is about (which may or may not be true). Not to mention the fact that people often regard the dictionary as the ultimate authority on what ‘real’ something-ism is about, cheerfully ignoring all its variants and flavours (which often blur into mainstream something-ism and each other), whose proponents are usually well persuaded that their own something-ism is the real thing—others just got it wrong.

There’s actually a third problem too. Namely, that if they’re not careful, something-ists who are a bit too zealous might end up putting their ideology before the reasons they embraced it in the first place. Sometimes, this can undermine the very objective something-ists intended to achieve with their embracing the ideology and spreading it left and right.

I had a brilliant example of this phenomenon one time when, while having lunch at a vegetarian restaurant (or vegan, I’m not sure), I mentioned lab-grown meat to my friend. My friend is a vegetarian (or vegan, I’m again not sure), whereas I am not. Vegetarianism and veganism are, obviously, two ‘-isms’; as a corollary of the above, I’m neither a vegetarian, nor a vegan. (Although again according to the above, perhaps I should say ‘vegetarianist’…) I’m not just quibbling about definitions: I do indeed eat animal products of pretty much all kinds. This, however, doesn’t prevent me from sympathising with the cause of vegetarians and vegans who are such because they’re against animal cruelty. Quite frankly, even if animals are raised in the best possible way, and are then killed in the nicest possible way (whatever that means), eating them is still at odds with my own moral compass. Even though I do eat them.

Overpopulation is the most common objection people make to developing rejuvenation biotechnology and potentially increasing healthy human lifespan. We take a look at why that is and if the figures support this concern.


Any discussion of rejuvenation biotechnology almost certainly includes the subject of overpopulation and that objection medical advances that directly address the various processes of aging will lead to an overpopulated world. Such dire predictions are a common theme when advances in medicine that could increase human lifespans are concerned.

Overpopulation is a word that gives the simple fact of population growth a negative connotation. It implies that an increase in the number of people will harm our lives in different ways: it might be famine, scarcity of resources, excessive population density, increased risks of infectious diseases, or harm to the environment.

This concern, first raised by the work of 18th century Reverend and scholar Thomas Malthus, has been a constant theme in both popular fiction and early foresights related to population growth. But is it actually well-founded? Let’s take a look at the issues behind these concerns from a scientific point of view.

If we ever want future robots to do our bidding, they’ll have to understand the world around them in a complete way—if a robot hears a barking noise, what’s making it? What does a dog look like, and what do dogs need?

AI research has typically treated the ability to recognize images, identify noises, and understand text as three different problems, and built algorithms suited to each individual task. Imagine if you could only use one sense at a time, and couldn’t match anything you heard to anything you saw. That’s AI today, and part of the reason why we’re so far from creating an algorithm that can learn like a human. But two new papers from MIT and Google explain first steps for making AI see, hear, and read in a holistic way—an approach that could upend how we teach our machines about the world.

“It doesn’t matter if you see a car or hear an engine, you instantly recognize the same concept. The information in our brain is aligned naturally,” says Yusuf Aytar, a post-doctoral AI research at MIT who co-authored the paper.

Can we live to 1,000? It was outrageous when he said it at ideacity in 2008… and again in 2015. Now he’s back to update us on the incredible progress that has been made toward life extension.

An international team led by the University of Chicago’s Institute for Molecular Engineering has discovered how to manipulate a weird quantum interface between light and matter in silicon carbide along wavelengths used in telecommunications.

The work advances the possibility of applying quantum mechanical principles to existing optical fiber networks for secure communications and geographically distributed quantum computation. Prof. David Awschalom and his 13 co-authors announced their discovery in the June 23 issue of Physical Review X.

“Silicon carbide is currently used to build a wide variety of classical electronic devices today,” said Awschalom, the Liew Family Professor in Molecular Engineering at UChicago and a senior scientist at Argonne National Laboratory. “All of the processing protocols are in place to fabricate small quantum devices out of this material. These results offer a pathway for bringing quantum physics into the technological world.”
