A better planned economy than what could be done in the 20th century. In particular, the way that many western countries' education systems and job opportunities are completely mismatched. It doesn't even have to be some advanced AI thing. Just some modern computer-assisted statistical work. For example, a population of N size will need N amount of primary school teachers, N amount of secondary school teachers, etc etc etc. Then just match up population growth estimates with the time it takes to train someone for that job, and have that number of student spots open (plus some percentage of additional spots, to cover people who decide it's not for them, early mortality, etc) in the universities and colleges and trade schools.

I would like to see robots that kill landlords

honestly brain chips made someone other than elon musk. Imagine if you could use direct brain control for prosthetic limbs as if they were no different from organic ones, or perhaps even direct brain interface with other things, the possibilities are plentiful. would also be neat if those chips could be used to treat otherwise untreatable mental illness.

Some sort of public repository for the culmination of all human achievements in art, knowledge and culture

Damn, it’d be crazy if that existed in some form already

I would like to see it being used in the collection of data to plan more efficiently in meeting the overall needs of every person in a global communist society. Make the planning more accessible for regular people to see and give their input on, using the power of the internet's instant communication.

The combination of VR, BCI (+other biometrics), and Deep Learning has the potential to help us master the placebo effect and open up a whole new understanding of treating the body. Instead it's gonna be used by corporations to make Manufacturing Consent seem quaint.

A bidet that pats my corn hole dry with a fresh towelette.

I have a fantasy of a society that basically lives in symbiosis with AI. The AI would serve as a custodian of the Commons, providing us with information and resources while we live gamified lifestyles seeking out experiences and creating art and doing research to expand the AI's training data. Our lives would basically be like an RPG; Fleshing out our customized skill tree and living in a state of Flow while reporting our experiences, thoughts, and feelings back to the AI.

My dick is really small like 1.4 BP and I’m hoping technology makes it so that I have a bigger penis
