I often experienced that this backfired. Single machines are still constrained in their power and while it's easy to spin up additional VMs in the cloud, scaling a program properly to run on dozens of machines takes a lot of work. It can be faster to develop a program that is really efficient and can solve the problem on one machine than to develop faster only to then spend the time scaling it to a large fleet of servers.
- z3t4 9y agoI kinda regret adding the note about performance, because switching to a lower level language used to yield orders of magnitude more performance, but optimizers have evolved and today there's not much difference. Sometimes the higher level language will be even faster because of optimizations. And bad performance is often not to blame on the language, instead blame the programmer or more likely the business people as they think it's great to waste resources as it gives them an excuse to charge more.
- ska 9y agoused to yield orders of magnitude more performance, but optimizers have evolved and today there's not much difference. If this were true, you'd expect see a lot more native python and the like.
- deepnotderp 9y agoPython is interpreted so super optimizing compilers, SIMD auto vectorization and other recent goodies necessary to get that performance won't work.

- ska 9y agoPython is not always interpreted. And when it isn't, it's still slow.
