That's one theory, yes. Cooking food (with fire) makes more calories available, meaning less hunting required to support more individuals, and/or freeing up more time and calories for thinking. This allowed us to evolve bigger and more complex brains.

While it's not a given that fire is a hard prerequisite for an industrial civilization, it certainly accelerated our technological development. Fact of the matter is, we know of exactly one civilization, which is not enough to draw any conclusions. There's no real reason we know of that aquatic species cannot evolve into a technological civilization, we just haven't seen it happen. Fact is we don't really know how an intelligent technological species evolves. We only have guesses from our own history.

Fire, agriculture, electricity, AI.

Rank these inventions in terms of importance to humanity.

That's the fun thing, since we have only observed a single advanced civilization, and that one only indirectly through archaeological evidence, there's no hard facts to be had! We can only make guesses. We don't know what is and is not required to make an advanced technological species, and we won't have any answers until we meet another one to compare with.

AI is not important at all. Just make things more convenient, but is completely unnecessary.

It looks like you've already done so with the order of the sequence that you used.

Arguably they're all fire -- requiring/involving forms of combustion.

(Well, debatable about agriculture, slash'n'burn wasn't the only form of it, but it was common for land clearing at least... all we have now is one that involves combustion engines, though...)

Nuclear weapons and the control structure around their use and fossil fuels and the C-corporation and what it optimizes for will probably turn out to be more important to the long-term future of humanity and it's civilization.

Fossil fuels are another feature like fire. One of the leading theories is that the availability of extremely energy dense fuels is one of the primary reason we were able to industrialize, and that without those fuels industrialization would be vastly more difficult if not impossible.

Personally I disagree with 'impossible', but it would definitely be harder. There's a pretty good argument to be made for leaving significant quantities of fossil fuels in the ground for the next civilization. If we wipe ourselves out, whoever comes next is going to very badly need those fuels to rebuild an industrial base.

		There were copper & bronze age industrial sites. Esp Tin & arsenic bronze smelting sites. Complete with child labour, open pit mines, assembly line style processing, and heavy metal poisoning. E.g. Semiyarka, in present day Kazakhstan, ~1600 BCE. You can still see the environmental damage to this day from the air. Romans had industrial processes, too, for things like fabric / laundry cleaning. What's new in the 18th/19th century is full-on mechanization of industry. And the wage labour system to make it possible. Accompanied by acts of enclosure etc to drive the peasantry off the land and into factories. Also the mechanization of agriculture that went with that.

We have counter examples of human pods that never really achieved “civilization”.

What’s missing that make them more akin to orcas or wolves?

It is possible it is just time. Modern humans are considered to have existed for 300k~ years. Civilizations are about 6k years old.

So who knows. Maybe if you gave them an extra 10k years, they would have achived "civilization". It is not much for the scale of human existance. But it is longer than any of our civilizations has existed for.

For humans, I wonder if population size and density is also a factor.

That is, if there’s a critical mass and population size.

		And makes sense with agriculture and civilization coming together. Agriculture improved the carrying capacity of an acre of land dramatically from what it was from foraging and hunting.
