Other than collapsing the internet when every pre-quantum algorithm is broken (nice jobs for the engineers who need to scramble to fix everything, I guess) and even more uncrackable comms for the military. Drug and chemistry discovery could improve a lot?
And to be quite honest, the prospect of a massive biotech revolution is downright scary rather than exciting to me because AI might be able to convince a teenager to shoot up a school now and then, but, say, generally-available protein synthesis capability means nutters could print their own prions.
Better healthcare technology in particular would be nice, but rather like food, the problem is that we already can provide it at a high standard to most people and choose not to.
It would be unsurprising to me if a biotech gold-rush resulted in healthcare becoming a larger proportion of GDP, even if it produced miraculous results. We'd just have to scrimp and save and take out a reverse mortgage for generic re-transcription therapy or whatever instead of chemo and nursing homes.
We might be able to finally determine the factors of 21
Yep this type of pandora's box is scary. Our culture demonstrably has no good mechanism for dealing with these kinds of existential risks.
Humans are fortunate that nuclear weapons turned out to be very difficult and expensive to build even with the theory widely known. If they were something anyone with an internet connection could create we would probably be extinct by now. There is absolutely no guarantee that future developments will have similar restrictions.
If bio-engineering gets accessible enough that any random motivated individual can create a new super bug we're pretty much doomed. Seems like something to worry about!
Crispr would clash with the religious fundamentalists slowly coming back to power in all western countries. Potentially it will be even banned, like abortions.
we need human development, not some shining new blackbox that will deliver us from all suffering
we need to stop seeking redemption and just work on the very real shortcomings of modern society... we don't even have scarcity anymore but the premise is still being upheld for the benefit of the 300 or so billionaire families...
