It has IA in its name so that must count for something.

#5> The computer contained about 18,000 vacuum tubes, which were cooled by 80 air blowers. More than 30 meters long, it filled a 9 m by 15 m room and weighed about 30 kilograms. It consumed as much electricity as a small town.
Surprisingly light though...

#6Eniac was indeed impressive and an important milestone. I recommend the 1999 book "ENIAC - The triumphs and tragedies of the world's first computer" by Scott McCartney which is both interesting to read and very informative. Also the review of the book by the late Jean Bartik, one of the "computers" and thus an eyewitnmess, is very interesting: https://web.archive.org/web/20221101120020/https://www.amazo....
Though the article is very US focussed, keeping quiet that German engineer Konrad Zuse completed the Z3 in May 1941, five years before ENIAC, effectively creating the world's first working programmable and fully automatic digital computer. While ENIAC required days of manual cable patching to program, the Z3 was quickly programmed by a punched tape ("Lochstreifen"), and Zuse also has invented Plankalkül between 1942 and 1945, which is widely recognized as the world's first high-level programming language. The cooperation between Zuse and ETH Zurich eventually led to the first self-compiling compiler and eventually Algol 60 (see "The European Side of the Last Phase of the Development of ALGOL 60" by Peter Naur in ACM SIGPLAN "History of Programming Languages" from 1978). And there was also the British Colossus, which was also a "programmable computer" and successfully utilized vacuum tubes for code-breaking by early 1944.

#7ENIAC was very important but this article overstates its significance and ignores other (non US) machines to the point of historical inaccuracy. No mention of Z3 or Manchester Baby for example, the latter based on the von Neumann paper for example, was arguably a more accurate pointer towards how computer architecture would develop.

The Z3 was only general purpose by accident, and this was only discovered in 1997 (published 1998). [0] It's only of theoretical interest because the technique required is too inefficient for real-world applications.
ENIAC is notable because it was the first intentionally general purpose computer to be built.

The vacuum in the tubes weighs nothing, so they produce lift.
