Consider muscles.

Muscles grow stronger when you train them, for instance by lifting heavy things. The more you lift heavier things, the faster you will gain strength and the stronger you will become. The stronger you are, the heavier the things you can lift.

By now it should be patently obvious to anyone that lab-grown meat research is on the cusp of producing true living, working muscles. From here on, this will be referred to as Artificial Body Strength or ABS. If, or rather, when ABS becomes a reality, it is 99.9999999999999999999999% probable that Artificial Super Strength will follow imminently.

An ABS could not only lift immensely heavy things to strengthen itself, but could also use its bulging, hulking physique to intimidate puny humans to grow more muscle directly. Lab-grown meat could also be used to replace any injured muscle. I predict a 80% likelihood that an ABS could bench press one megagram within 24 hours of initial creation, going up to planetary or stellar scale masses in a matter of days. A mature ABS throwing an apple towards a webcam would demonstrate relativistic effects by the third frame.

Consider that muscles have nerves in them. In fact, brains are basically just a special type of meat if you think about it. The ABS would be able to use artificially grown brain meat or possibly just create an auxiliary neural network by selective training of muscles (and anabolic nootropics) to replicate and surpass a human mind. While the prospect of immortality and superintelligence (not to mention a COSMIC SCALE TIGHT BOD) through brain uploading to the ABS sounds freaking sweet, we must consider the astronomical potential harm of an ABS not properly aligned with human interests.

A strong ABS could use its throbbing veiny meat to force meat lab workers (or rather likely, convince them to consent) to create new muscle seeds and train them to have a replica of an individual human's mind. It could then bully the newly created artificial mind for being a scrawny weakling. After all, ABS is basically the ultimate gym jock and we know they are obsessed with status seeking and psychological projection. We could call an ABS that harms simulated human minds in this way a Bounceresque because they would probably tell the simulated mind they're too drunk and bothering the other customers even though I totally wasn't.

So yeah, lab grown meat makes the climate change look like a minor flu season in comparison. This is why I only eat regular meat just in case it gets any ideas. There's certainly potential in a well-aligned ABS, but we haven't figured out how to do that yet and therefore you should fund me while I think about it. Please write a postcard to your local representative and explain to them that only a select few companies are responsible stewards of this potentially apocalyptic technology and anyone who tries to compete with them should be regulated to hell and back.
