There were "perceived shortcomings" although Smalltalk use seems to have grown in the decade following. IBM taught "object-oriented software technology to experienced procedural programmers" and studied that experience — 'We read and heard many stories about confident and experienced programmers' plunging into self-study tutorials, only to give up in frustration after several hours, still wondering, "Where is the application code?" … New programmers often became lost in the hierarchy or spent considerable time in unfocused exploration of the interactive tools.' https://mitpress.mit.edu/books/making-use https://mitpress.mit.edu/books/making-use Technical shortcomings, September 1988 — "… currently unrealistic to expect that an excellent rapid prototyping system can also be an excellent application delivery system." https://static.miraheze.org/triplescriptswiki/4/49/Wirfs-Brock_and_Wilkerson_-_1988_-_An_Overview_of_Modular_Smalltalk.pdf https://static.miraheze.org/triplescriptswiki/4/49/Wirfs-Bro...
