Thats what we are, nothing comes from nothing, we all build on the work of others sometimes because of their work and sometimes in spite of it.
The modern world has so much information available but people take very little time to let it percolate and stew, instead they publish quickly and get feedback quickly.
This easy accumulation of information does not allow time for it to become knowledge, for them to ‘know’ it.
Our ancestors had less information available but more time to think.
Don’t flit like a bird, be calm, ruminate and know.
