What scientific idea is ready for retirement? Steve Giddings: "Spacetime. Physics has always been regarded as playing out on an underlying stage of space and time. Special relativity joined these into spacetime, and general relativity taught us that this spacetime itself bends and ripples - but it has remained part of the foundations of physics. (...) The apparent need to retire classical spacetime as a fundamental concept is profound..."

"The current scientific description of space-time - a cornerstone of such a theory - is inadequate because quantum mechanics is at odds with general relativity. To explore deep questions that may one day help resolve this longstanding paradox, UC Santa Barbara theoretical physicist Steven Giddings has received a $100,000 two-year grant from the Foundational Questions Institute (FQXi). (...) Although the concepts of special relativity and quantum mechanics fit together nicely, general relativity and quantum mechanics are much less harmonious."
So the spacetime of Einstein's special relativity should be retired, according to the first quotation. The need for that is profound. According to the second quotation, spacetime is inadequate but this time only general relativity is to blame while "special relativity and quantum mechanics fit together nicely".
FQXi should be renamed MFDF ("Money For Deranged Friends").
