Is There a Barrier to Machine Learning?

There's an awful lot of data running ond in the world, offif social media. It feels strange that we don't have enough data to be able to make this work. And sometimes we cannot even collect this data. Our regulations, in many cases, don't allow us to collect full data. That elgrin my need. Some algrims such as deep learning, require millions of data points to make it work the best. So if the size of the data base is critical to making sure that we have enough to train the augarithm on,. and potentially have a broad enough base that some of that bias could be minimized.
