Golem

 The Mishna Verura (55 - sk4 ) quotes the Shaila  of the 

Chacham Tzvi, if  a Golem who was created with 

Sheimos (Sefer Yetzirah)  can be used for a minyan.

Since the Mishne Verura is a Halacha L'Maaseh Sefer we must 

assume that the Heiliger Chofetz Chaim held there will 

be a time in his lifetime  or after, when a Godol  will be 

capable and might even create a Golem.

Another possibility might be the Chofetz Chaim held  

scientist might one day create a Golem (robot with 

artificial intelligence) 

The Poskim will be able to refer the Chacham Tzvi's 

Teshuva to determine if we can or can't use the robot 

for Minyan.
