If the last-mile problems of things like autonomous vehicles have been anything to go by, it seems the last mile problems of entrusting your entire business operations to complete black box software, or software written by a novices talking to complete black box, will be infinitely worse.

There's plenty of low-code, no-code solutions around, and yet still lots of software. The slice of the pie will change, but it's very hard to see it being eliminated entirely.

Ultimately it's going to come down to "do I feel like I can trust this?" and with little to no way to be certain you can completely trust it, that's going to be a harder and harder sell as risk increases with the size, complexity, and value of the business processes being managed.
