Advantages and disadvantages of electronic tour guide and manual tour guide

The biggest advantage of manual tour guide is humanization, which is alive rather than dead. The disadvantage is that people are different. If you meet irresponsible or mercenary people, it will make people uncomfortable. The advantage of electronic tour guide is that you can go wherever you want, walk as fast as you want, and walk as slowly as you want. It won't be unhappy because of my behavior. Of course, it won't change because of my mood. It's a bit rigid.
