we have a way to go

I bumped into the fascinating paper on physical limits of computing. I never expected any references to black holes, but here it is... As far as we know, black holes have the highest information density in the universe. It is on the order of 1066 bits per cm2. I looked up the density in Seagate hard drives. It is somewhere at 1010 bits per cm2.
A black hole with the surface the size of a Seagate hard drive has the capacity equivalent to 1056 hard drives that we use today. That's incomprehensible like probably everything about black holes. However in the last 50 years, we increased the information density by about 108 times. If we continue at this rate exponentially, it would take us only around 400 years to reach the limit.
