j245··on Intel Shows Off Multi-Chiplet Sapphire Rapids CPU with HBM
Imo this is a bad analogy. I would say it’s more akin to Kia and BMW.

The proportion of potential users priced out of owning a Mac vs. a PC is much lower than Ferrari vs. Kia

What I mean to say is - customer base for Mac vs. PC overlap alot and aren’t distinct as you seem to be alluding to.

j245··on Solar-powered aircraft flown for nearly three weeks without landing
This record was set ~3 months after someone else did it for 50 days.

From an engineering stand point, performance of components or materials are always assumed to be much worse than actual and the forces / conditions they are subject to overestimated, with further factors of safety applied on top. This is how it should be. It also means properly designed things will carry on working better than you expect (on average).

It’s not interesting (to me) from a technological stand point compared to the solar UAV because flying up and down the same road with a truck refuelling you is not useful, and if others (e.g. Military, NASA) could be bothered to do it - they would probably do a better job relatively easily.

To me - It’s the same as building the worlds longest domino trail. You could beat the previous record by 1 million dominos which is neat but.. what have you proven, and why does it matter ?

Neat - but not interesting from a technological stand point.
j245··on The $150M Machine Keeping Moore’s Law Alive
I’ve always wondered - would the effort to develop such software be lower, because the hardware is more forgiving.

In which case you are trading human (software development) time for hardware resources.

If that were the case, it seems like an okay-ish trade off to me tbh.

Why pay 5x ?

If you wait - you’ll get a 20x machine at current prices.

This is what Moore’s law is about ? I.e. Density (~= proxy for compute) doubling at some fixed period.

Phew ! - That’s only one or two years of suffering for the Afghan population.

Who cares ?! /s
