help me look into the future of chatbot

we all use chatbot and few of us use it for almost "everything". we all know what it does, what it lacks, what can be improved.. so i was just wondering.. what can be done or what is that the public wants from the chatbot that it is lacking currently..? or.. if we go way beyond.. like.. 30-40 years from now, what do you want the chatbot to do then.. or something that can be implemented now and can be used for next 50 years maybe.. actually there's a project im working on and im concentrating more on this domain.. so.. looking for suggestions.. 😊
