Maybe that's why Google has made a few dozen amazing things while FB has made basically one thing and acquired the rest. A culture that respects engineering leadership.

It's hard to think of something amazing from Google that they didn't acquire other than the search engine. Maps, YouTube, Android were all acquisitions. Most Google internal projects are future entries in the "Google graveyard". The better stuff I can think of is mostly deep technical stuff like Map Reduce built to support search. Facebook has also done fairly well with things that are pillars to support the (formerly) namesake product.

Chrome, Gmail, drive, Chromecast, duo, call screening. There are plenty of entirely home grown products that have succeeded. Discounting products which have had the vast majority of their growth and featureset built out while under Google is also a but dismissive of it's role in making them successful.

duo has been successful?

GMail, various chat things, GSuite, Google Brain, Google Translate. Maps, Android, and YouTube were all massively developed and scaled after the initial acquisition.

Most of their post-2000 successful products stem from acquisitions: Docs, Maps, Waymo...

Docs was an acquisition? From where?

Started out as a product called Writely in the mid-2000s. Got bought by Google not long afterwards.

Not sure if it’s still the case but until fairly recently you could still see writely in the different domains Docs cycles through when logging in.

Version 1 was from a company named Writely. Google massively refactored and rewrote it afterwards though.

Writely. Company was called Upstartle.

i dont think a tech company will move away from a engineer centric focus, everyone which dared disappeared. Oracle as patent company is a different story
