Can someone give a proper counter-argument to this?

I keep telling my friends hyped by bitcoin that I do not believe in its future as a currency for real daily exchanges because of this energy consumption problem.

Is there any serious track to address this issue?

Unlike most technologies, I do not see the traditional efficiency gains when the technology gets more mature. It seems inherent to proof-of-work and cannot be improved in this paradigm

Assuming a solution is found, is it possible to "update" Bitcoin?
