Personal note: automl algorithms in this field will bridge the gap and automate several key processes, but it will not allow a practitioner to do serious research or solve business or product problems easily. The importance of this field is to advance each subfield, whether HPO, NAS, etc. these selective novelties can help us solve specific issues, i.e, lets take HPO, we can use it to save time and money on redundant parameter searches, especially when it comes to resource heavy algorithms such as Deep learning (think GPU costs).
