Default Ripples in spacetime do exist but spacetime itself doesn't

Steve Giddings will retire spacetime and will only live for the ripples in the retired spacetime:

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... [...] The apparent need to retire classical spacetime as a fundamental concept is profound..." x

" In celebration of Einstein’s birthday, physicists reflect on the German-born scientist’s work and its impact on the field and on everyday life. “We have good reason to believe general relativity is not a complete theory and, in particular, that it’s going to break down in the context of describing black holes,” said UCSB physics professor Steve Giddings. “That’s very much an important problem in physics today. “The direct observation of gravitational waves from colliding black holes really constrains the possible departures from general relativity that we know are there and limits where modifications can be made,” he continued. “But the discovery is still spectacular and its announcement was one of those moments in science that you live for.” "

This is Einstein schizophrenic world isn't it?
