I've always loved emergence. The entire universe is founded upon it, from physics to chemistry to biology to neuroscience and genetics, and beyond. There's a field of math called complex systems analysis which basically just studies emergence, and if I were more mathematically capable, I would definitely want to make that a source of income. Whenever people say something is "too complex" to be chance or physics, I'm just like, "no, it's not; emergence happens all the time". I would even consider emergence a fundamental property of the universe: scale anything up enough, mix enough simple bits together, and you get something complex and more capable than the sum of the parts.

I've been following transformer-based AI research quite a bit since the first announcement of GPT-3 (though admittedly not as much as some people, for sure), and these emergent spikes have excited me. Especially when you consider that a rat neuron is nearly identical to a human neuron, it's only the number of neurons and the connectivity that separates a human brain from a rat brain. (By analogy to AI, that'd be the number of parameters and their learned values, respectively.)

Emergence: it's everything, everywhere, all at once :)
