I can hold out the hope that successful founders will enter other industries with their next startup.
I was pleased to see that the RFS series included ideas for software-hardware combos, but I was disappointed that the example was Meraki, since they're still, AFAIK, mostly software.
Although the new funding formula is a step in the right direction, it remains exclusive of ventures needing more than just the living expenses of the founders.
Specifically, I perceive a tremendous market inefficiency in RDBMS implementations, which, even at modest scale, end up costing too much for (often "hosted) hardware and/or don't perform. However, because the point is to do a better implementation of something that is otherwise costly, even the proof of concept is likely to require upwards of $15k in hardware.
Granted, it could be leased, but, if that means buying brand name, the amount financed could easily double, perhaps even triple, which would be $5k-$8k over 4 months and a subsequent excessive drain for the remaining 20, if they occur.
The $100k LoC BootUpLabs offers is almost enough to overcome their unfortunate location and incubator model, since it may well result in a complete, launched product, with no debt baggage.
Of course, this is still an order of magnitude below where VCs would come into play.
My bet is on YC branching out of tech startups and perhaps getting into seeding businesses in traditional industries. I would go as far as to say that they're due for a presidential meeting; if the economy doesn't improve, they might even be called in to testify before congress (remember how easy it was for the l0pht to appear in congress?) a government appearance will put them on the spot.
The closer of a mirror to YC an imitator gets, the further they get from the intent that makes YC possible and successful.
I also want to say this might be the first PG essay that I not only liked, but agreed with. Usually I enjoy, but disagree with him.
