Yes Segwit2x is very necessary at this stage, with the demand increasing, this fork should happen soon or later to solve some of the problems you mentioned (biggest problem was a few weeks ago when loads of transactions were stuck on the blockchain). However, I have not read any news regarding this hard fork, it was postponed but no date is known for now. Probably early 2018.
It's actually not necessary because Bitcoin is not utilizing the current capacity to its limit, it's too early to talk about the block size increase while we had one just a few months ago.
SegWit2x failed because because there was just 1 developer and he made a lot of mistakes so his software came out bugged. After this fiasco the chances of SegWit2x succeeding decreased to near-zero, because they were pretty low even when everything seemed smooth for it - despite support from miners and businesses, it never had support from community and developers.
Thanks for your point of view!
I hear a lot lately that Bitcoin is more a digital gold than a usable currency.
Digital currencies have to be scalable to support global economy, they need to process at least hundreds of transactions per second to start being used as a currency, but to replace giants like Visa they would need many thousands of transactions per second. Currently, cryptocurrencies with the biggest blocks can theoretically process only a couple of dozens of transactions per second, but their blockchain would quickly bloat, making it impossible to run a full node by average users, resulting in a quick loss of the most valuable property of cryptocurrency - decentralization.
