In the last 15 years we got reusable rockets, mRNA vaccines, Crispr, workable quantum computers, AI capable of beating us at Go, and many other numerous breakthroughs. Sure 1900-1910 meaningfully changed the world but the bar form the 1800's was dramatically lower than the 2000-2010 bar from the 1900's. Ironic that such a ignorant comment laments societies ignorance.
