Nearly any uses for flexible electronics would also be satisfied by sufficiently small electronics such that lack of flexibility doesn't matter.
Eg. rather than having every pixel in your flexible screen be flexible, you make each pixel rigid and have the joints between pixels flexible.
In this case, this design is based on SERV, which uses ~2100 gate equivalents, which in a recent tech node would be 40 um^2. That means you could fit a 10x10 grid of these in a single pixel on an iphone screen.
I really can't think of a use case where a region 1/100th of an iphone screen pixel being rigid would be a problem.
