I don't agree with your comment. $50,000-$100,000 of well placed funds with the right software consultancy can generate a project that pulls in enough cash flow to pay for itself multiple times over in just the span of months.
Machine learning is not a high return investment on its own. It is only leveraged as a technical piece of an already cash flow healthy larger pie in most organizations.
The division of labor and supply of various workers makes most labor intensive tasks self-explanatory in cost.
$300,000 can buy you a property that takes years to double in value in comparison. They're completely different categories of capital utilization.
