Good point! I wonder if we’re spoiled by computer invention though. Would be interesting to compare preWW2 invention rates and now. I suspect computers just made everything else easier, but now we’re back to hard problems

To be fair, there’s only been 24 year’s of 21 century. Most things you gave listed happened at the end of the 20th century. But also the question is somewhat self negating - we won’t know what’s the greatest invention until we see it working great, but it takes much more than 24 years to take an invention from concept to consumption. For example computational biology is kicking off. Computer aided dna generation started in the past 24 years. But it’s so new few people think about it. Just like no one thought of internet as the greatest invention in the 70s… it was just too new
