The interesting thing about technology breakthroughs is how quickly the shift from the impossible to the banal actually is. An example of this is machine learning. This was something that was being researched on since the 1950s, with very little to show for it in terms of practical applications. This changed very recently, thanks to the growth of computing power. Now, many of these same techniques are used in many things that are taken for granted, like language translation, image recognition, and surfacing content in algorithmic timelines of social networks (not all utilisation of this technology is good).
This was one of the first thoughts I had when I heard about the announcement of a potential vaccine for malaria, which uses very similar technology to the mRNA Covid-19 vaccines.
