I am reminded of this quote from Joseph Tainter & Tadeusz W. Patzek's 2012 book, Drilling Down: The Gulf Oil Debacle and Our Energy Dilemma:

"Boiling a frog is a metaphor for the problem we all have perceiving changes that are gradual but cumulatively significant, that may creep up and have devastating consequences: a little increase here, a little there, then later some more. Nothing changes very much and things seem normal. Then one day the accumulation of changes cause the appearance of normality to disappear. Suddenly things have changed a great deal. The world is different, and it has been altered in a manner that may not be pleasant."
