I've had enough, first the click farmers, and now Planters© peanuts!
Wait...maybe I'm just hungry.
Or, more realistically, you're an idiot.
What they're trying to say, albeit poorly, is that from the waiter available for irrigation, drinking water, pools, lawn care, etc., a large amount is being used for irrigation. Because there is a shortage for everything else, they're saying about is being used for irrigating various crops, which in turn adds up to how much is being used for meat production.
Just because they say how much is being "used" doesn't mean they are implying it is gone forever. There is a finite supply (at current climatalogical conditions) of fresh water to use at one time. If you drain a lake to irrigate crops, the lake is still dry even if the water is still in the local environment.
If it is the Satoshi Nakamoto, there is a pattern: a complete lack of the understanding of how personal privacy works on the internet.
The fact that he's fairly old adds to the evidence. If he were in his mid 20s he'd never have used his real name or outted himself because he'd understand how privacy works (or rather, doesn't work) with respect to the internet.

Yes, you can do parallel startup with System V. You also can make a systemd init process that doesn't do anything in parallel.
Yes, systemd is smarter with dependencies in the sense that it has dependencies and not a numered list. Yes, you can have a System V script that manages it's own dependencies, but because you can do an infinite number of things with System V scripts many people have tried. I've ran across dozens of System V scripts that are hundreds of lines long even without couting the standard ".
In the end, yes, it's another config language you'll have to learn, but it's worth it.
System V has a scrict sense of a run level. For example, if you want a full desktop, run level 5 is often used, for a headless server, run level 3. What if you have a box that is headless most of the time, but you want to be able to run a full desktop sometimes? With System V you would change from run level 3 to run level 5 which would, depending on implimentation, stop and start services that are needed by both. Systemd instead has the concept of targets. Your full desktop target would have the headless server target as a dependency, and starting the full desktop would only run what isn't already running. You typically also have individual sevices that have dependencies. For example, you'd want your dhcp server to wait to start until the network has come online. In System V you have to define network as a number and make sure everything that depends on it has a bigger number and everything it depends on to have a smaller number. systemd's dependency model is also smart enough to start processes in parallel.
All of that is just the most exposed part of systemd (to me at least). It also supplants other processes such as xinetd and udev. Instead of having three different ways to start processes based on system events (startup, port connection, hardware event) you have a single system to manage all three. It can get complicated (wasn't udev already complicated?) but the consistency is worth it.
To keep all the consitency systemd provides a series of functions and magic variables. By magic variables I mean you set a list dependencies, which IMHO is less magic than the chkconfig comment lines in a typical System V init script. Both the magic variables and functions mean your typical service initaliation script is 10 lines instead of 100. While they may not be as obvious what's going on (a System V script is self-contained and can be ran on it's own) it is once you've become familiar with them.
