I have three areas and I believe there are business possibilities. But is that so ?
Art
I am alone. I currently have subscription to Clip Studio Paint Pro. Art in animation requires audio and music support. Meaning team. Currently unable to make or get into team. Cabinet have passed bill on animation development at National Informatics Center. But no chance of placement there as I am about to retire. Animation seems out of question. Also AI is a big challenge to animation. Business development ruled out.
Mathematics
Mathematics is a professorial field. An application of my mathematics and interest of business group over the mathematical application are crucial to make it a business. My KAAL number theory may be of interest to premier management institutes for Ramanujan theta functions development and focus development. But the chances of a business group and me and a premier management institute getting together is ruled out. Business development ruled out.
Music
I can make songs. But there has to be quality and multi-tracking. Which means sound proofing. Buying many hardware and software. These are expensive. I need loans. Are these possible? Business development ruled out.
There are cries that there are no jobs. And I want to help create jobs and opportunities. Political parties also want new jobs.
But ultimately nothing gets materialized.
