This is the equivalent of a guy building a "car" in his backyard with old used parts, then saying it was only 1% of the cost of a new Mercedes, and everybody thinks now that Mercedes is 100x overpriced.
Also the "calculation" is totally wrong. A guy with lots of enthusiam and masses of free time rebuild existing tech stacks in plain PHP (!) and JS (!), two of the slowest languages on the planet. That alone should debunk the whole story. Comparing ANY logic in PHP vs C (nginx) is just nuts and ChatGPT should know it.
Interesting hobby project, and maybe even a profitable one if you find niche clients, but obviously far far away from the definition of a 0.01% engineer.
