Ok. That was easy for you, so lets open a can of worms.
What does the Buddha say about technology? Is it pointless? Is it redundant? Is it unnatural, good, bad? You know that it has resulted in many deaths, so what about that? Should we get rid of our electrical and chemical technology and live without it?
Why are there gods and demons in Buddhist writings?
Should humanity embrace one language or should it continue to have multiple languages?
Heh, you do like to ask the good ones (lol)
The Buddha wasn't aware of our modern technology of course, but I think he'd say if it can be used for good- do it. I don't think it is always used in a good way. Most of our modern technology could be used for good though. Like I think we're using the internet for something good. Buddhists try to think about what is skillful, and that includes what is expedient. I don't think we need to go to the extreme of getting rid of technology.
There are gods and demons in Buddhist writings because we very much affirm the unseen realm. Historically at least because not all modern Buddhists believe in these things. I do, however, so you're in luck. For us gods are the unseen beings described in the Vedas and various world mythologies. They brought about some of the conditions we exist in here, as the world of forms goes. Some of them are good and some malevolent. Some have taken refuge in the Triple Gem, which means they became Buddhists essentially. One deity said to have done this is Indra.
Demons are beings in lower births/realms in Buddhism that envy humans and the gods. Some Bodhisattvas like Jizo and Kuan Yin have made emptying hell realms their priority.
I talked about faith aspects of Buddhism earlier and the gods happen to be one. In the sense that the Buddha had the awakened eye of enlightenment, and it's said could see deities clearly. He spoke with Brahma according to accounts of his enlightenment. I have asked the Devas for things on occasion and had miracles happen. In Buddhism it is also seen as good to be kind and loving toward these beings, since we believe they exist. In every daily practice, I ask all deities that might be present to take refuge in the Triple Gem if they please.
I think languages are skillful means. Meaning what put them to the use of having a society, but one language would suffice if the world is ready.
