More improvement in the area of vaccine technology, acceptance, and adoption of these techniques: alternative forms of administration, less reliance on boosters, improved thermal stability. A better understanding of the immune system, neuroscience, and human biology in general. I expected more infectious diseases to be eradicated such as HIV, TB, and malaria.

These things are progressing and I see hope in how technologies are progressing, but I believe vaccine and infectious disease research and development have been severely limited by the industry's obsession with intellectual property and pursuit of profit. Our understanding of human biology has improved, but thinking back to my teenage years, I was naive as to how complicated biology is and how little we actually understand.

I'm still a bit salty no one ever brought dinosaurs back from the grave. Our progression in flight technology has been disappointing without flying saucers too.
