Cuprate high Tc superconductors (HTSC) may hold the promise of lossless 
transport of electrical power, a net positive fusion power generation 
and quantum computing devices, but after more than 35 years of the 
discovery and intense research, the mechanism of HTSC in cuprates 
remains unresolved. Here, I will present capabilities of angle-resolved 
photoemission spectroscopy (ARPES) and show that this technique is 
perfectly suited to provide a smoking gun evidence for the pairing 
mechanism in cuprates, just as the planar tunneling was for conventional 
superconductors. I will present the ARPES studies of a prototypical 
cuprate, Bi2Sr2CaCu2O8+d, in a wide range of doping, covering not only 
the superconducting dome, but also its endpoint on the overdoped side 
and the non-superconducting metallic phase. Our studies suggest that the 
resolution of high Tc problem might finally be in sight by providing a 
direct connection of the detected coupling effects with 
superconductivity. I will also indicate some of the new directions where 
the ARPES and HTSCs, in combination with other materials, might continue 
to amaze us.
