Why?

 

Across the country, hotels are moving away from traditional human customer service and instead imploring the use of robots to boost hospitality. Room service is a staple of the hotel experience, and thanks to innovation in artificial intelligence, robots are used to deliver meals and several other services to guests. Hotels have received nothing but positive feedback from the addition of robots. Hospitality will certainly not be the only area of society that will experience a spike in automation, and it appears people are growing more accustomed to that reality.
