In Part I we discuss accumulating experimental evidence related to thestructure and origin of the bosonic spectral function \alpha ^{2}F inhigh-temperature superconducting (HTSC) cuprates near optimal doping. Someglobal properties of \alpha ^{2}F such as number and positions of peaks, areextracted by combining optics, neutron scattering, ARPES and tunnellingmeasurements. These methods give convincing evidence for strong electron-phononinteraction (EPI) with 1<\lambda \lesssim 3 in cuprates near optimal doping.Here we clarify how these results are in favor of the Eliashberg-like theoryfor HTSC cuprates near optimal doping.We argue that the neglect of EPI in someprevious studies of HTSC was based on a number of deceptive prejudices relatedto the strength of EPI, on some physical misconceptions and misleadinginterpretation of experimental results.
