If journalists keep writing articles about tech bubbles every few months, someone is bound to be correct. Looks like this "trend" started up again in 2013.
I do see a slowdown but this is nothing like dot.com. Seems like a normal correction and is not really separate from the rest of the economy being uncertain. Nothing tech specific.
Bubble is an overused term. An inflated market is not a bubble, and a correction is not a bubble bursting. Markets go up and down all the time.
i.e. Not A Bubble.
Right now it looks like a gentler reversion to the mean in GDP growth from the peak of this 6-year business cycle, which was much less pronounced than previous business cycle peaks.
But who knows - the failure of a large firm that was generally thought to be solvent could set off another crash.
Someone invested in a mutual funds or index funds will have pretty little exposure. Sure Apple, Google, Twitter, and Facebook might lose some value, but those aren't a huge portion of a diversified portfolio.
Even the first web bubble only had modest real impact on the general economy. It put the country into a shallow recession for a few quarters but that was it.
Even worse was pouring money into things like Nortel after the crash was well under way. People just chased it to the bottom.
Edit: I thought I'd add that even in a bloodbath like 2001, not everything tanked. The (tiny) company I was with continued to grow in revenue. We weren't doing anything glamourous, just focusing on business value. No IPOs, although some folks were trying to push us that way in the late 90's.
I don't know what I'm saying I'm just saying it with data.
