Excel is ingrained in day-to-day work of current working generation. It will be difficult to replace (barring select-few companies).

I strongly feel that post-generation-Z (born post 2001) workforce will expect (and work towards developing) better decision engines - powered by better technologies. This generation is using some form of AI/ML in day-to-day life, in schools, colleges. They wouldn't expect anything less in work. This will get progressively better.
