Humans have a lifetime of data, but you can easily parallelize the model such that it takes in more data than a human can in his/her lifetime, and still humans are still the state of the art.
Not only mention those fields that require lab work, practical field work, and/or specialized equipment or facilities to learn. This site is far too CS and math specific sometimes.
