Personally, I would welcome this, as I'm pretty bored of the altcoins following BTC's trend. Even if some big names criticise Bitcoin, but not any other coin, makes the whole market drop, while only Bitcoin should. This may change easily, and I'm hoping for it.
As I see it, Bitcoin is technically outdated, and I see no point of it other than everything trades into it.
I get your point, but for me, it all comes down to where you put your trust in. I personally value BTC much much higher than USD.
To me, it only makes sense to trade vs BTC. Bitcoin is my reference point, because it is ultimately the currency I would like to keep.
As for being technically outdated, I have to disagree. When billions of dollars are at stake, you need no fancy untested technologies.
You need a stable, tested code, a code backed up by excellent developers that has endured the test of time.
Otherwise things like the Ethereum DAO hack or similar hacks are just around the corner.
