When an experienced scientist like you says something like this, I pay
attention. Other should too. The current obsession with "productivity"
is an invitation for a "don't think, just act" mentality. Everything
that cannot be turned into a potentially successful paper doesn't
mater. And so, we through away the more subtle insights. Maybe we
throw away the stuff that actually matters.
When did you stop believing in atoms?

I agree.
