I'm going to predict there will be a movement into "build it in house with LLMs", these things are going to be expensive, they are going to fail to deliver or be updated and there will be a huge bounce back. The cost of writing software is very small, the cost of running and scaling it is there the money is and these people can't have their own IT teams rebuilding and maintaining all this stuff form scratch.
A lot of them will try though, just means more work for engineers in the future to clean this shit up.
