If you prove we will not see over 10 TB HDDs in mass production in the following 6 years, then you can get some big blockers more sceptical about scaling above 2 or 4 MB. So go ahead.
You said 10-100TB, which implied a tenfold increase in 6 years. This is not likely.
All we have to do is loudly demand 100TB hard drives be available in 6 years.
Obnixious repetitive complaining will force those lazy, stubborn, greedy bastards at Seagate and Western Digital to come up with a solution.
That's how engineering works, right?

How dare those bastards censor us! We will start a new subreddit r/100tbHardDrives and show them what everyone wants. Nevermind that the engineers have told us repeatedly told us they can't make 100TB+ HDD's at this time, WE WANT IT AND WE WANT IT
