This is not a new sentiment, and maybe nothing to worry about:<p>&quot;It is said that what is called &quot;the spirit of an age&quot; is something to which one cannot return. That this spirit gradually dissipates is due to the world&#x27;s coming to an end. For this reason, although one would like to change today&#x27;s world back to the spirit of one hundred years or more ago, it cannot be done. Thus it is important to make the best out of every generation.&quot;<p>― Tsunetomo Yamamoto, Hagakure: The Book of the Samurai
