The first thing you must realize is that it won't be too far till owners realize what you already said and shutdown the business or give it to contractors.
From what you wrote I can only see a big opportunity. sometimes it is hard to see opportunities at hand. You should consider yourself lucky because you already have the tools, the time and potential investors, first start with automating your job (create an automated pipeline that does what you are supposed to do, this will help you learn a lot and help you to think of new projects for the company ) but you must create another position or a project proposal for yourself first haha . I had a similar situation years ago, and I decided to take trainings (and earned certificates) if i were in same situation now I would take a proactive role and create tools and systems that add values to my team/company, and show it to the bosses and advance myself and the company, and loop.
it is very very unlikely that you will achieve this in your current life. lol. the easiest approach for you is to get rich and buy a ticket to space. ( e.g. like the south african guy who created ubuntu he paid millions of USD to go to space)
I think he is being realistic and i think he did a good job, you wouldn't write this if you asked him or if you knew things like worst-case, average-case, and best-case performance.
