You're crazy if you think Kyrgios didn't feel what was spent in that match. It doesn't matter your age, it's about fitness and Murray is probably the fittest guy on tour. Krygios isn't even maybe 50% as fit as Murray. Kyrgios reminds me of Dimitrov a couple years ago. Supreme talent, but he's still got to get that fitness level up. There will be plenty of Grand Slam matches where he might not get pressed enough for it to matter, but guys like Rafa, Djokovic and Murray will work that angle.

Doesn't mean he cannot compete, but if Murray crafts the match to involve rallies - Kyrgios will get gassed IMO.
