I think it depends on how you view it. With 20x productivity you can start to minimize your supply chain and reduce costs in the long term. No more cloud usage in foreign countries, since you might be able to make the necessary software by yourself. You can start dropping expensive SaaS and you make enough for your own internal needs. Heck, I would just increase the demand because there is so much potential. Consultants and third-party software houses will likely decrease. unless they are even more efficient.

LLMs act as interfaces to applications which you are capable to build yourself and run your own hardware, since you are much more capable.
