Your message is vague as vague can be. It also doesn't help that the word "algorithm" is sufficiently general to cover any piece of code.
We want smarter machines, and that means making algorithms more widely available. To achieve that, we're creating a community around algorithm development, where people can contribute code and collaborate with others on that code. Github has done a great job of this, but it is not always trivial to get from a github repo to live code in production. We think that creating a built-in market for algorithms-as-a-service could be a way to reward algorithm developers for their work, and make algorithms easily accessible via REST API.
The types of algorithms we are talking about is not limited by us. My opinion is that the most useful algorithms in the near future will be related to: machine learning, classification, analysis, and optimization. There are also numerous applications for things like image recognition, speech-to-text, and translation, to name a few.
Good luck... that seems like a really intimidating area to learn and a collection of ready to try algorithms could be super useful.
