A decentralised pseudonymous reputation system, so that your good-standing in one online community (platform/silo) can be visible to people in another online community.

The answer might involve some sort of web-of-trust solution, and storing proofs on a blockchain, but the hard problems are how to avoid Sybil Attacks and not exposing people's social graphs.

Code editor that fully embraces power of VR, and treats code not as text, but as AST. Imagine every node of the AST on it's own plane, with every related signature or declaration just one vim-style keystoke away, opening right next to the previous one, instead of above it.

There's nothing impossible from the technical side, but figuring out what is actually useful and time-saving in terms of UX and what would just end up as useless eye candy would require enormous amount of work, I'm afraid.

Isn't it one of the goals of Urbit?

I’ve long been interested in the “cocktail party problem” which involves disambiguating audio in a conversation with multiple people. I think this tech is foundational for better video calls and smart speaker devices for homes. The best research I’ve seen on this is from Mitsubishi but as far as I know this is well into the territory of an impossible problem today.

There's been a ton of interesting research and progress on this in the last few years: https://ai.googleblog.com/2018/04/looking-to-listen-audio-vi...

A bot that uses ML to trawl through all your social media accounts, get a good sense of what you would post, and then starts auto-generating posts for each platform, for you to review.

You look at them once a day, select the ones you want to publish or just click select all, and it publishes them, appropriately spaced out over a 24 hour period.

Not impossible but hard: create an application that lets you talk and auto-generate code/pages for an app. There are lots of companies working on this but you might be able to find a good niche.

I can't believe we still don't have a standard tool that lets a user design a CRUD application right from server back-end to front-end.

Also, federalizing social networks. I know that Mastodon exists, but the impossible part would be making something like that truly popular.

Also, speaking of social networks - giving people the ability to automatically sync their charity contributions to their public social profiles, as in "I'm donating 7% of my income to these causes, and 3% to those" (using some properly designed API from tax authorities) and making it popular enough so that most part of the population is socially nudged to some accepted level of regular charity donations. In my libertarian fantasy, it would gradually replace taxes, but yeah, I'm aware of how idealistic and far-fetched that sounds.

I think they do exist.

Ruby on Rails and similar for example.

Microsoft Access and similar is a bit older but does that too I guess.
