As I said, I highly doubt that people will accept Metaverses at this stage.
It's way too early. The infrastructure around a lot of these metaverses are incomplete and game mechanics are too complex to understand properly.
Will you bother to learn so much about a metaverse just to bet $5? Or would you just put $5 on roulette on Roobet...
The same thing was once said about computers, the Internet, and e-commerce. But today these technologies are no surprise, because we use them every day. Metaverse will not be limited to one thing as for example gambling but will give users a wide range of entertainment and leisure. Take a look at how many users congregate in The Sandbox every day and you'll see the future. Rumor has it that Mark Zuckerberg is developing his own metaverse. I don't think he's going to invest his money in unpromising projects.
As long as the idea would benefit others, it is OK. The issue here is that some individuals have a difficult time accepting new technologies since they prefer the traditional way. They are not open to new ideas and continue to undervalue such fresh meta in this industry. If these people are not interested in these new innovations, then claiming that they are worthless is nonsensical because you are only presenting your own personal opinion while overlooking other people's positive interest in this innovation.
Innovation and progress cant really be avoided or an inevitable thing and of course each people do have different impressions and views thats why we cant really force them on what we do want for them to be.
For now then it would still act up for people to observe whether they would be considering it or would stick out on traditional things that we've been used to.
We do have our own choice and preference thats why it isnt surprising these kind of views.
