I had watched a handful of science-related videos on BT's YT channel. Can't remember how I got there originally, but most likely via the excellent
long interview Neil deGrasse Tyson did with Stephen Colbert, from there more Tyson clips eventually got me to BigThink, I'm pretty sure.
The link in the OP piqued my interest enough to watch ("neurons change when we do/think something new/differently" idea) and I don't believe in "addiction" per se for internetz, but I can't deny it's been a real focus-killer in my life, personally. But I shared for discussion, not blind acceptance, obv.
Anyways, back to work I go... Must Resist Internet Timesinks
