Which makes sense because a browser is basically a set of abstractions over some normal OS functions that blends remote and local actions (even if only a subset of them).
Java wanted to be a universal VM, but browsers actually achieved this through HTML and JavaScript. They're going even farther with WASM.
Java succeeded, you know. Still happily powers embedded systems, servers, and desktop applications. Still runs the same binaries on NT/Darwin/Linux/Haiku/whatever. Don't dismiss it just because it's not the latest hotness.
The only holdouts I see are stuff where Java is part of the standard (e.g. SIM cards using Java Card standard) or embedded systems where they use Java of some sort where it doesn't make sense to use the enormous browser runtimes (although I have to imagine that's a less popular option than C, but I'm not super informed on the embedded market).
I mean, I'm not particularly a fan of where this is heading (it feels like we're heading for the second coming of Java applets/flash and all those associated problem), but it seems pretty obvious, to me at least.
But when you consider the fact that browsers these days are essentially operating systems in their own right, complete with a suite of bundled application functionality (e.g. WebRTC, WebGL, SVG, etc.)... it seems pretty reasonable.
Right-click on it and go to Show Package Contents. Then navigate to Contents > Frameworks > Google Chrome Framework.framework > Versions
You'll also see a symbolic link to 'Current'. Right-click > Get Info. on that to see which folder to 'not' delete.
I've got 2 versions (230.1 MB and 228.7 MB). The commenter I was responding to therefore must have 3. So the "real" size is ~230 MB, which does seem pretty reasonable, and totally in line with Firefox as well.
(For comparison, Calibre is 207 MB, Gimp is 224 MB, and Kindle is 210 MB, while Word is a whopping 2.11 GB, and Photoshop is a similarly gigantic 2.45 GB.)
Obviously it can't do everything Firefox & Chrome can - it doesn't even support CSS gradients, and has the worst font antialiasing I've seen in a while - but it's fast and lightweight. Apparently the minimum requirements are a 30Mhz processor and 16 Megabytes of RAM - it was originally designed for PDAs and set-top boxes.

Its lack of modern JavaScript support also makes it good at getting around news website paywalls, if you're so inclined.
Say, while I have your attention, have you considered mirroring your site on Gopher? These text-mode Gopher browsers are superfast, with none of those "PNGs" and "JPGs" that slow everything down. 2020 should be the year of Port 70 on the Desktop.
(Just kidding... mostly. I may have opened a Gopher account at SDF.org during my quarantine....)
