The world could run on older hardware if software optimization was a priority

I like to point out that since ~1980, computing power has increased about 1000X.

If dynamic array bounds checking cost 5% (narrator: it is far less than that), and we turned it on everywhere, we could have computers that are just a mere 950X faster.

If you went back in time to 1980 and offered the following choice:

I'll give you a computer that runs 950X faster and doesn't have a huge class of memory safety vulnerabilities, and you can debug your programs orders of magnitude more easily, or you can have a computer that runs 1000X faster and software will be just as buggy, or worse, and debugging will be even more of a nightmare.

People would have their minds blown at 950X. You wouldn't even have to offer 1000X. But guess what we chose...

Personally I think the 1000Xers kinda ruined things for the rest of us.

Except we've squandered that 1000x not on bounds checking but on countless layers of abstractions and inefficiency.

Am I taking crazy pills or are programs not nearly as slow as HN comments make them out to be? Almost everything loads instantly on my 2021 MacBook and 2020 iPhone. Every program is incredibly responsive. 5 year old mobile CPUs load modern SPA web apps with no problems.

The only thing I can think of that’s slow is Autodesk Fusion starting up. Not really sure how they made that so bad but everything else seems super snappy.

Slack, teams, vs code, miro, excel, rider/intellij, outlook, photoshop/affinity are all applications I use every day that take 20+ seconds to launch. My corporate VPN app takes 30 seconds to go from a blank screen to deciding if it’s going to prompt me for credentials or remember my login, every morning. This is on an i9 with 64GB ram, and 1GN fiber.

On the website front - Facebook, twitter, Airbnb, Reddit, most news sites, all take 10+ seconds to load or be functional, and their core functionality has regressed significantly in the last decade. I’m not talking about features that I prefer, but as an example if you load two links in Reddit in two different tabs my experience has been that it’s 50/50 if they’ll actually both load or if one gets stuck either way skeletons.

I'm on a four year old mid-tier laptop and opening VS Code takes maybe five seconds. Opening IDEA takes five seconds. Opening twitter on an empty cache takes perhaps four seconds and I believe I am a long way from their servers.

On my work machine slack takes five seconds, IDEA is pretty close to instant, the corporate VPN starts nearly instantly (although the Okta process seems unnecessarily slow I'll admit), and most of the sites I use day-to-day (after Okta) are essentially instant to load.

I would say that your experiences are not universal, although snappiness was the reason I moved to apple silicon macs in the first place. Perhaps Intel is to blame.

5 seconds is a lot for a machine with an M4 Pro, and tons of RAM and a very fast SSD.

There's native apps just as, if not more, complicated than VSCode that open faster.

The real problem is electron. There's still good, performant native software out there. We've just settled on shipping a web browser with every app instead.
