Why Blockchain is good for us # 2

Hello,
Today I would like to continue the topic why the blockchain technology is so good for us. I am reading news and articles about blockchain for at least half of a year. My goal is to learn someting new about new technology like blockchain and so cryptocurrencies every single day. And of course I would like to share my thoughts with people to make is usefull for other people.

I found another great YT video about the blockchain - greeting to its author for great content. I would like to share it with other people. On the video below, there was mentioned some great ideas about blockchain usage in the dayliving. For example:

• creating new kind of social media, (like steemit)
• machine learning
• buying cars and other goods withous thousands of intermediaries and so fees
• creation of massive transactions/per second - bitcoin is quite old but it is still the beginning
• environment- we can get a cryptocurrencies for recycling the plastic bottles by bringing it to the plastic bank, machine etc.

I would like to discuss some problems which may happen in the future like :

• what will happen with all the data in the blockchain?
• will the information be in blockchain forever ?
• if everything will be registered in blockchain, what would happen with privacy ?

Check the video and give some thoughts about advantages and some problems in the future
