Ethereum was unusable for a long time because of a single 150M dollars ICO.
Are you sure ETH would handle real world use?
You can ignore all the issues Bitcoin has had in the past all you want Johnny Bravo.
The point is not that Bitcoin doesn't have problems. The point is that
both have problems, and therefore ETH is not necessarily superior.
It's also important to realise that if updates can be passed
too easily, it usually means the coin is centralised (if it's quite large like ETH). Bitcoin is currently quite a fringe movement for free money, and ETH compromises this, which is why it's usually not accepted by merchants - because BTC is the free money, and ETH not only is centralised but isn't even much better anyway!
It doesn't matter what speculators seem to the price of Ether to be. Once LN is implemented, I regard it to only be useful for smart contracts, and I see that as unrelated to BTC/not in competition.
In the future some cryptocurrencies could well be better than BTC, but this doesn't mean that all of them have to be adopted by merchants.
