Some technologies are very difficult to learn all on one's own without relevant experience, either personally or within a team. Or to put it another way, you could solve your specific problem by hiring experts. But it would still take them some time to implement a solution despite their expertise and experience. Computer science and software engineering are hard. Image recognition was developed by large well funded teams of engineers over many years. Not solo-developers in an afternoon. Some technologies require person-years for proficiency.
