Should I use VPN?

I will argue that you should use a VPN because it is necessary to keep your data secure.
The internet is an amazing tool, and has enabled so much progress for our species. It gives people in developing countries unprecedented access to the world’s knowledge, and allows us to communicate with each other like never before.
Unfortunately, it is also a very dangerous place. Hackers can easily steal your identity or access sensitive files by exploiting unprotected connections. Companies monitor and record your behavior online in order to sell you products that they think you want.
They can do this through the use of encryption algorithms, because it is impossible to convert plain text to ciphertext without knowing the decryption key. This means that even if your data is intercepted by a third party, they will only see scrambled and unreadable messages.
There is one problem with encryption algorithms, though. They are often slow and resource intensive. This means that they can be difficult to use for many applications.
Another issue is that encryption algorithms are usually secret, or proprietary. This means that users have no way to know whether they could be using a weaker form of the algorithm.
