Agreed. Warren wins the Internet today.

[*] The absolute XFS filesystem size limit is about 8 million terabytes, which requires about 500 cubic meters of the densest HDDs available today. You'd need 13 standard shipping containers (1 TEU) to transport them all, without any space for packing material. If we add 20% more disks for a reasonable level of redundancy and put them in 24-disk 4U chassis and mount those chassis in full-size racks, we need about half a soccer field of floor
space --
something like ~4000 m^2 -- after accounting for walking space, network switches, redundant power, and whatnot to run it all. It's so many HDDs that you'd need four or five full-time employees in 3 shifts to respond to drive failures fast
enough to keep an 8 EiB array from falling over due to insufficient redundancy. You simply wouldn't make a single XFS filesystem that big today, so QED: effectively unlimited.
Let's see, how many grad students did the first digital computer need to replace the burned-out tubes? Was it about that many?
But I agree, he does win the 'Net for today. I propose we award him one (1) valuable resource... say, an IPv4 address. <g>
