So, might I propose that this is actually a symptom of a larger problem (which you seem to hint at) – irrational exuberance and the (re)inflation of a tech bubble that's getting dangerously close to its peak?

I've gotten downvoted for this idea recently, but I really do think that the signs are there – there's a supply/demand imbalance in the labor market because money is flowing easily and everyone's getting funded (thus inspiring more startups who further compete for labor)

So, either this means that there are tons and tons of great ideas (with equally good executions/plans) out there right now or we're seeing a return to the wild days of bubbles-past. In either case, however, it's likely not genuinely sustainable.

Sure, there's some reason to see a lot of genuine, sustainable growth in the tech world – the world's going digital so old markets go into a new medium, either with old players pivoting or new players supplanting them – but my gut tells me that's not all that's going on here.

But, then again, I'm probably just pessimistic...
