It will be less stable, but I think I agree with your analysis ( and in real terms, when was it really stable .. 50s? ). Oddly, I think it may only add to the 'Previous team didn't know what they were doing. Fix it.' vicious cycle. In a sense, companies will be re-inventing the big 3 consulting companies.

It is not just just English and skill set that is the issue. In my neck of the woods, I just dealt with otherwise really smart data guy, who was giving me something that clearly did not make sense in the business context - not everything can reasonably be placed in a requirement ( assume earth is not flat ).
