I have found a common pattern between critics on any field (web vs web3 for example). When your financial stability depends on the industry you are currently at, you will always find a way to defend your current state and critic the others. It is very uncomfortable to hear bad things about your future...

Interesting observation! It's true that people often feel threatened when their livelihood is tied to a specific industry. Remaining open-minded and considering different perspectives can help us adapt to changes and grow professionally.
