Good points. Somehow typing latency might actually be better, lol.
V8 might just invent like 3 more execution engines though, 1 of which uses an external TPU (open source though!) to run code JITed to HVM (Higher Order Virtual Machine) that everyone is eventually compelled to adopt, one can't be too sure JS will lose. /s
20x more compute isn't much in terms of cryptographic security concerns, no? Ah but triple-DES was recently depreciated.
Definitely sounds right that we'd get an earlier, heavier emphasis on parallelism and hardware acceleration. I'm guessing the slower speed of causality also applies to propagation delay and memory latencies, so there wouldn't be new motivation for particular architectural decisions beyond "God please make this fast enough for our real-time control systems or human interaction needs".
If we got deep learning years or decades earlier, that also seems scary for AI existential risk, as we are just barely starting to figure out how the big inscrutable matrices work, and that's with the benefit of more time people have had to sound the alarm bells and attract talent and funding for AI interpretability research.
Sounds right to me. Without being able to rely on flashy visuals and low-latency so much, games would've had to be somewhat more strategic and intellectual to sell (although I imagine graphics would eventually catch up due to its fitness for parallel processing). Even if brain rotting visual spectacles were just pushed 7 years down the line, they still would probably have a more sophisticated flavor that might be cemented with time (e.g. this counterfactual TikTok might have given users much more direct control over their feed algorithm).
