> I hope to see a lot of things in my lifetime: life discovered outside our planet, human cloning, artificial organs and blood, AGI, humans on Mars, cures for a broad spectrum of cancers and Alzheimer's, human life extension / slowing aging, broad advances in chemistry and materials science, major advances in metabolomics, protein folding, drug discovery, gene therapies and repair... The same list of things people were 'hoping for' in 1988. (From personal experience; probably a high estimate.) We're not a iota closer here in 2019. Wishful thinking isn't enough; no matter how hard you hope and how much money you waste, you're not going to make a fundamentally better airliner or horse buggy.
