Hardfork Constantine and Petersburg

[Jk]

Ethereum’s next two network upgrades, called Constantinople and St. Petersburg, are scheduled to take place this week at block height 7,280,000, which is expected to be mined on today. Moving from the purposefully computationally expensive Proof of Work (PoW) model, also somewhat unaffectionately known as ‘proof of waste’ due to its high energy costs, to Proof of Stake (PoS) consensus protocol will make the Ethereum network faster and transactions cheaper.
What do you think about it?

I am happy to finally see Ethereum moves on with the upgrades, to be honest, I think the future is for POS, we can't just keep doing POW coins  because at some point the energy of the world won't be enough, we all know that there are some countries already suffering from the mass mining of Cryptocurrency.

It is great news from Ethereum. They begin to fulfill people expectation about new hard forks on ETH. I have already know about Constantine, but I am surprised to see Petersburg. Is this a new plan that is created to support Constantine? Or I miss news related to this hard fork.

As I remember that I have read somewhere after this upgrade ETH will have the function call reverse contract, meaning that when you join an ICO, if you think the project won’t success, you can withdraw your ETH back from the project owner wallet

Due to Bitcoin dump we cannot see ETH rise higher at the moment, the main reason for traders like me to hold ETH is we expect a pump of ETH with this upgrade but it seem we fail now
