The lightning network will not quit too quickly. Although everyone is in urgent need of the lightning network. This requires a lot of testing, and has played a game with the miners. Let's look forward to a team that doesn't use the news for us in 2018.

Agree, many people whining about the transaction fees and the transaction time while they didn't utilize the features that bitcoin have which is Segwit. All people expecting Lightning Network to solve the scalability of Bitcoin.

Bitcoin right now is very much affected by the scalability problem which became the basis for the ridiculously high transaction fees which many are really complaining about since this is what Bitcoin should be; we did not signed up for this, so to speak. Appropriate and acceptable solution has to be found and implemented before the whole world will go sour on Bitcoin and jump to other more viable cryptocurrency. Within the cryptocurrency market, the competition is quite fierce on who has the right to kick out Bitcoin from its throne that is why Bitcoin devs should work hard and make it fast without sacrificing security but not also using it as an excuse to delay things from happening. I am expecting the Lightning Network once fully implemented can be the answer to the problems of Bitcoin right now. Of course, it may not be perfect but that is much better than the status quo. We should hope that once it can be available, exchanges will implement the said upgrade without hesitation and another round of politicking.

As you said the competition in bitcoin becomes very tough so bitcoin need to be developed soon to stay in the game otherwise some coin will replace bitcoin if the high transaction fee and slower transaction keep persisting long.But lightning network was already tested in testnet and it will be implemented on mainnet with 2018.

It would be an interesting dynamic if merchants (ie. BitPay) where to implement LN before most major exchanges. Meaning, people would have a higher incentive to use BTC as a means of payment instead of trying to dump it on the next exchange whenever the chance arises.

Also, whatever exchange is first to offer LN will likely have an edge in terms of liquidity, as people would be more likely to deposit with them.

Either way, very valid concerns. I hope LN is easier to integrate than SegWit, albeit I fear that this won't be the case.
