Why concord failed?

I read the write-up of one Mr S M Mansoor, Gulshan who found out the reason of Concord's failure.

When this aircraft was developed in late fifties and early sixties, that is, before the western rockets were fired in the outer space, was the supreme achievement in metallurgical science and pure jet engines. The outer skin of the aircraft was a sheet of high grade Titanium to withstand the very high and very low temperature. The inner layer of the fuselage was impregnated with the outer skin in a manner, which was not known to metallurgical experts of advanced countries, till the time space capsule was fired in the space.

As the concord breaks the sound barrier twice to reach 1450 miles per hour which is double the speed of the Earth's rotation on its axis and faster than a rifle bullet, there is no unusual sensation inside the cabin. You experience only an increased engine thrust. No "sonic booms" are heard inside the aircraft at any time. The only sound is a unique "sizzle" of rushing air, higher in pitch than is heard in subsonic air travel. At 65,000 feet altitude, you can view the curvature of Earth.

For Mr Mansoor's information, I would like to inform that at 65,000 feet altitude the temperature is minus 76 degree Fahrenheit. The very high speed of concord produces enough friction with the atmosphere to cause outside air temperature to rise by over 400 degrees as it passes the tip of the aircraft's nose. This friction is so high as to melt the metal of an aircraft which is not streamlined and outer skin is not technically meant to withstand this heat. As the air streaks past the fuselage, it is still hot enough to boil water. Mr. Mansoor perhaps has no clue to such development of material science.
