I think something like this wins that category: https://en.wikipedia.org/wiki/Eastern_Interconnection
I suppose it's partly a semantic question that hinges on what you count as a single "machine" and what's a system or a network.
Hey, author of the piece here. Glad people seem to have enjoyed it. If you're looking for more sources on ASML/EUV I put together a bibliography of things I looked at while writing the piece https://neilhacker.com/2026/04/28/asml-article-bibliography/
Who ruled this the most complex machine? And by what metric?
I think, if one were used to calculating cyclomatic complexity, such a headline is not only amusing, but also fascinating even if it is 'wrong' by .. some value system .. because the thought exercise to come up with a more cyclomatically complex machine, is rather a fruitful challenge. And that is why writers should be allowed to editorialize, because .. after all .. this is a thought-provoking article, isn't it ..

You can't make desktop computer 4 times larger but there's very little preventing you form putting 4 racks where you had 1 before. If the floor space is the expensive part of data center then probably some incentives are misaligned.
Bigger chips = more distance to cover for your electrons = more power required = more generated heat = slower throughput for your data. Surely you don't believe that the entire chip industry had not thought of "wait what if we just make the chips bigger".
Same reason that so much work was put into increasing wafer diameter over the decades.
More chips per wafer means a lot.
Much more than for performance sake.

There's a thing in writing where you can make bold claims in order to give the reader an idea about what the rest of the article is going to be about - that's whats happening here, a bit of editorializing .. but do you know of a more complex machine than the ASML/TSMC production line, in terms of inputs/outputs? I think, if one were used to calculating cyclomatic complexity, such a headline is not only amusing, but a…
It's been mentioned before, but Chris Miller's Chip War from a few years back is an excellent, very-readable book on the topic. Goes into depth on the history and development of chips and their production. He did the rounds on the interviews back then, and it's definitely worth a read. The EUV stuff is great, but I particularly liked his history on how the USSR was always going to lose and how integral Apollo really…
Chip War is an interesting book, but it has a lot of errors, which made it frustrating to read. For instance, it said that vacuum tube computers were hardly usable because they attracted moths, so they required constant debugging and were only used in specialized applications like cryptography. This is wrong in many ways. Most notably, Grace Hopper's story of the moth was in the Harvard Mark II computer, a relay comp…
Is the ASML machine actually the world's most complex machine under some metric, or is this a claim that someone made up? I.e., did someone actually compare the ASML machine to the Space Shuttle, LHC, Internet, and so forth and show that it is more complex under some definition? (I've done various historical questions, so I'm sensitive to how statements are sourced.) An orthogonal question is what makes sense as a me…

so it had an unusual amount of inputs and outputs? that's the measure?
However, let us continue to postulate there are other forms of complexity that can be measured - what would you suggest are the other 3 or 4 contenders for the title?

Non-zero chances - yes. Unavoidable - I wouldn't be so sure. I can't imagine how many top human-hours and cutting-edge inventions involved to construct this machine. And much of this simply cannot be stolen or bought, no matter how much money you have.
It has never happened in the history of the world that a company or country could maintain its technological advance indefinitely. Either China will catch up on this or that particular technology will become obsolete. But it is certain that they won't stay behind forever (measured in a small number of decades at most).
You might place an upper limit using history but in this case I'd guess that limit would end up being much larger than the present semiconductor industry itself might last.

Off topic: Does it blow anyone else's mind that a DRAM chip has more transistors on it than there are humans on the planet?

I don’t know that many people would classify the Space Shuttle as a machine. It doesn’t make anything.
