While I personally doubt that for $17M one could build such a vacuum robot prototype (for a vacuum cleaner company, investing this amount of money - if it worked - would be a rounding error), I will rather analyze the point that you raised:
It is a very common situation that the workflows of companies is deeply ingrained into some tool
- that they can't get rid of (be it Microsoft Excel (in insurance and finance), be it Git (in software development), ...)
- that is actually a bad fit for the workflow step (Git and Excel often are)
So, this is typical for the kind of problem that companies in sectors in which billions of $/€ are moved do have.
I am actually paid to develop some specialized software for some specialized industrial sector that solves a very specific problem.
So, in my experience the reason why nobody [is] solving actual problems (in the sense of your definition) anymore is simple:
- nobody is willing to pay big money for a solution,
- those entities who are willing to pay big money often fall for sycophantic scammers/consultants.
