> That is in no way diversification. And the correlation of investments within the tech world, when shit hits the fan, will be 1.
Hence the "in a way." And your argument makes the assumption that tech, as a category, will collapse.
> Which of the companies are making profits?
"Tech" is a very big thing, but if we're picking random companies there are a few divisions:
Public: Google makes money hand over fist, Amazon tries not to make profits (and almost accidentally brought in $20m last quarter) while their revenues grow exponentially. Facebook brings in billions, Twitter, the dark horse of this category, is still bringing in >$1B/yr in revenue.
Ok, but those are the titans. Let's look at the YC companies: Airbnb, Dropbox and Stripe alone would make up for every dollar YC ever spent investing.
But even locally, almost every company I talk to is choosing to raise money. Meaning, they have enough revenue to stay afloat, but elect to raise money to grow more quickly. These are companies raising little $2m rounds but are either profitable or could be if they needed to, but elect to grow quickly instead of become cashflow positive. (Admittedly, my company does not fall within that category).
There may be overvaluation, especially at later stages, but the investments being made assume there is. They assume that some (or most) will fail, but that the others will make a multiple.
Some money will be lost, but as long as the entire category of "technology" doesn't collapse altogether, it's not like 1999 again. And given the amount of real profits and revenues in the category of "technology," my contention is that there won't be, as Marc Andreessen puts it, an "earth-shattering kaboom."
