I wonder if this is the right timing?
Uber/Airbnb don't need near the amount of product/engineering they actually have.
AirBnb is...a database of static listings and a search engine on top. Their top technology problems were all solved by Expedia like 20 years ago.
Expedia, hotels.com. booking.com and most airlines are handling more requests than Airbnb in more challenging environments.
They have thousands of engineers sitting idle or making pet projects, struggling to justify their existence, as regularly attested by internal employees when an article pops up.
