What's amazing to you? The fact that when something better and more realistic comes along, people prefer it?
Isn't that a little bit of a redundent and meaningless comment?
Real-time Path tracing is a technique used to achieve a more realistic light simulation than previous real-time techniques. From the looks of DLSS 5, layering this technology on top makes it more realistic still.
Which is how progress works. Every time a new technology comes out, do you refuse to prefer it, simply because the best that was available previously had been your preference up until then?
By that logic, surely you would still be playing pong on an old Atari from 1975.
It's precisely the increase in realism and it's potential to increase it to levels that were unimaginable before, that is exciting.
