In all seriousness, have you ever tried digitizing old journals? It is fairly time consuming.
No, I have not tried to digitize old journals. But I HAVE helped contribute to the digitization and distribution of public domain works. I'm aware of the time and financial resource commitments involved.
Writing an encyclopedia is time consuming, but we did that.
Walking & driving all over the world is time consuming, but the OpenStreetMap community has done that.
Scanning & digitizing old public domain books is time consuming, but the Project Gutenberg project has done that.
What's next?
