Searching a niche to focus on and create some value for me and others. Any business ideas?

I’m searching for a job/duty (in a sole proprietorship or in a company)

Skills to use
Programming (Python, HTML, CSS) (or a new language), Finance related, writing, consulting

Niches that interests me
Drop-shipping, AdSense, affiliate, webshops, AI, deep-learning, Python coding (in general)

Are there any new trends/jobs/niches that contributes to/will change/revolutionize the world in the coming 10-20 years? Maybe make jobs obsolete. And create opportunities for others?

I guess AI(/deep learning) is one such niche, which can be divided into many other niches. I like to hear what you see as game changers or just different ways of doing things?

Thanks in advance
