Centine

Quite interesting, but the final point - not to worry about lock-in seems a little ridiculous to me. First off, it may hold for a simple product built in 12 hours but I have not yet seen a magic bullet that reduced the complexity of rebuilding software by several orders of magnitude. If you have something that took 2 years to build, it's not probable that cloud functions would reduce the rewrite barrier to anywhere near zero.

Secondly, there aren't that many alternatives - yet. This will probably be remedied.

Not necessarily the NSA, but I don't particular trust either Google, or especially Facebook if they launched something like this, to not be listening to ad-related keywords.
