> But this type of freedom comes at a cost that some do not want to pay. Who are those some? Managers or techie? Because yes, business choose to do it's best avoiding Smalltalk, Lisp etc for business reasons, but those reasons are not "their cost" but the fact that with them anything is open, integrated, there are not countless of individual "product" to be sold, well welded so to guarantee that no one can temper them etc. It's a bit like modern "open source enterprise" monsters, they are not monsters because doing so make easy changes people involved in a project, find people skilled in that field etc but because being monsters it's cheap to pay enterprise support instead of deal with issues internally, re-write from scratch instead of forking etc. While these days Smalltalk and Lisp are just programming environments on a host OS in the past they were the OS and so the OS is a unique environment not a container cargo ship with containers on top, anything rigidly separated, that's the business reasons behind industry choice IMO...
