Too early to talk about the century, no? But for the last 20 yrs, my top 5 would be:
1. iPhone & Appstore (introduced by Google, adopted by Apple)
2. mRNA vaccines
3. Bitcoin & Ethereum
4. Human Genome Project (not a "product")
5. Model S
Others things could make it to the list in the next 10 yrs - chatGpt, CRISPR
