The parent post is not implying that companies adopt Tensorflow themselves and solve this problem. The post is implying that a competitor come in to the market using the newer, better technology, and replace them with a better product (with an API, documentation, etc). This issue here is that industries become stagnant when it appears difficult/costly to introduce a new product in that market. You usually need significant a technical and/or social change to occur before incumbents can be displaced. In this case, it was a technical change. The other part of the issue is that investors want "0 to 1" ideas to invest in, and founders often chase those ideas. In reality, we need more "1.0 to 1.5" products, especially in crowded markets.
