[Harry Potter] Is the so-called "magical Renaissance" over? Is the wizarding world on its way out?

I am a wizard, and this is my first time using a muggle computer, but I should be safe asking this question from any exposure to muggles given this neat little obliviating hex my Professor taught me holds up. 

I am away at academy, and I try to be a good student. I want to learn as much about wizarding culture as I can, which, yeah, attracts some bullying or namecalling from time to time.

There's this one prick, though. Wilfred Pesk. He's raised by scientist muggles, so he prides himself on knowing things others don't, and making sure everyone knows how smart and keen and "red-pilled" (some muggle reference?) on social sciences he is. He's the most nihilistic, pessimistic, and downright rude individual I have ever met in my life. He loves to poke fun, saying things like "The magical Renaissance is over", or "spells aren't made anymore, anywhere". And I know that's not true, for the most part. 

But he said something recently that really kinda got at me. I was reading up on the Wizengamut and the political system in the British wizarding community, when Pesk showed up and started taunting me.

He said something to the effect of, "Give it a rest, will you? There's no population growth, there's no desire to study magic, there's massive stagnation scientifically and sociologically, huge xenophobia, and general apathy in the population. Everyone is comfortable, and that's the worst thing a country could be. This is how Byzantium fell, this is how Rome fell, this is how every apex country in the world fell, and it's how the wizarding world will fall, too." I asked him how he was so damned sure, and he said "I dunno, why don't we have any idea what Magic really is? Why aren't we still researching and making spells every day? Why are there so few magical creatures still around? The magic is leaving the world, buddy." And then he fucking left. 

I'm mad but I can't help but entertain his thinking. His history at least seems sound, from what I know. Is the wizarding world on its way out? Are there any references to this that I can read? What will replace wizards as the new "apex society", if so? Or, what could prevent this stagnation?

Typical Brit, always thinking the world revolves around you. You do realize the the UK is the magical equivalent of the short bus right? Nothing but angry squabbling inbreds who refuse to look outwards. There is an entire world of magic and spells out there.

And if he wants to brag about "science" go ahead, just remind him that scientists can even break the laws of reality like even a typical first year can do. And they call themselves advanced.
