I used to work in cancer research and I don't think it's fair to say that we're experiencing a revolutionary improvement. It looks pretty marginal to me. Sure, some cancers (the "easy" ones) are making significant improvements and grinding down on death and recurrence rates.
But most of what you are describing is forward-thinking, not an accurate description of today.
Were metastatic melanoma and NSCLC considered "easy" before immunotherapy? My understanding is that they were near certain death sentences.
I think that the progress so far certainly looks revolutionary compared with the previous few decades. I also agree though that a lot of excitement is related to perceived future benefits.
