Excellent OP!
These technologies are ubiquitous, and everyone uses them, so the amount of information is growing exponentially as well. People's attention span is short, but it is theoretically possible to make our information accessible to the few who are interested.
Today, there is no known method for making information searchable and accessible into the future, since file formats are quickly outdated. This is already a huge problem, which worries many archivists. 100 years is a very long period of time, and today's known companies and technologies will have been replaced by then.
Probably, humanity will change - with hybrids between humans and machines being created. These creatures will have longer life spans, and it will probably be possible to transfer all memory from one generation to the next. But as far as "memory," that kind of data processing may be very different from what you had in mind.
