Software seems like a very immature field where we can still do a lot to increase performance. I'm looking forward to the shift
It really does not require new expertise or tech at all to cut latency and load times by 90%. Programmers have to get back to being engineers instead of just duct taping libraries together or praying that the dumb GC knows what its doing
At most places, there’s barely enough time to implement things completely let alone to optimize everything properly.
It’s also noteworthy that optimizing 10kloc from yesteryear is a much easier task than optimizing a few mloc of code today.
We didn’t just lose all those optimized libraries. The requirements bloated and nobody wants to reduce features.
