I just synched my bitcoin core wallet and it and took a lot of space. (170 GB)
It is mostly bitcoin blockchain from 2009 to 2018. I Guess the number is allright whenyou take in consedaretion how much 1 tr hdd cost now.

I wonder how will look Bitcoin in the future. What about Segwit?
Growing of blockchain is a bit faster now.

What are your estimates that will be needed for example in 2030?

That is one of the problems that blockchain technology will have to solve. The size of the chain will keep growing as the number of transactions grow and this is a quite a problem. The advancements in this area like Ethereum sharding, BTC Lightning network will try to remedy this problem, but only the future will tell.
