Have you ever paid for educational podcasts (播客)or live videos? Ask some people and most of them will say yes. "Pay-for-knowledge" has been more and more fashionable these years. The contents of these "pay-for-knowledge" products are from language learning to gardening or baby-caring. Everything you think of can be found online at this moment. "Pay-for-knowledge" is on the rise(兴起).
Why is "pay-for-knowledge" industry developing so rapidly? First, its development is based on the Internet. With a fast network and a smartphone, anyone who has passed the identity(身份) check can be an online teacher, and anyone with an online account can buy "pay-for-knowledge" products that he or she wants at an affordable price. Second, people are afraid to miss any information. On one hand, people hope for more useful information.
On the other hand, such information is usually at the hands of experts (专家) who serve well-known companies and universities. Moreover, the need to learn new skills in today's job market also pushes people to learn on such educational podcasts.
The industry of "pay-for-knowledge" has proved to be lucrative. It promises possibilities of turning information into money. It is good for the development of our country and it can help sellers make lots of money. Besides, buyers can enjoy self-growth from it. What's more, this is a reflection(反映)of respect for knowledge and talents.
However, the rapid development of "pay-for-knowledge" has a few problems. For one thing, the market is full of eye-catching words such as "How to be an Industry's Expert in 5 Hours" and "15 Classes to Be a Master of Appreciating (欣赏) Classical Music", which sound like if you pay for it, you are sure to succeed. For another, a large number of customers buy them just for showing off. In fact, those who have really had self-growth after buying online courses may be the kind of people who need them least. In other words, with or without these courses, they can make it anyway, because they are those who have the ability to learn by themselves.
In general, the best is the one that suits you most. "Pay-for-knowledge" may be used as a good start for self-growth. Be careful! Otherwise, your dream of success may not come true.
