No, I think he means that the product of visual programming is often slow and buggy. Which I can agree with to a point - there is a price to pay for all these abstractions. From my own experience - the closer to the metal a product, the more performant and stable it is. In the past I was sure that game engines were an impossible tool in the field of engineering where the performance matters so much. Clearly, I was wrong (in large part because of the hardware improvements).
