1/ This is a brilliant talk. I appreciated it, in particular being both a computational physicist and a HW veteran.
The bad habits is SW were already spreading back in 2001.

2/ I’m wondering if there are still people around today who would be able to do something like E04DGF and CVode. I doubt that anything has improved at those levels. Is E04DGF still the fastest?
3/ The problem is also, that SW will come and bite the semiconductors, so the HW itself. After having done some work with Cadence I can only say: what a mess. It’s a patch and collection of pieces that they have procured over time. But nothing is consistent across modules.
4/ Back in 2001, we were still working somewhat low level and taking care in optimization of solvers. But the progress of HW made us lazy. Waiting 6 months for the better HW had better results than trying to squeeze out performance by e.g. preconditioning differential equations,
5/ ..the mathematical problem, e.g. by conditioning the matrices to make CVode run faster. My own laziness exploded in 2003 when I switched to Python from C++. More productive in coding, but a waste of HW use performance. I have never written a C++ line of code since then. 🤷
6/ I think that both SW and HW will collapse rapidly at some point. So what will happen then to:
electric cars
digital money
data in some cloud
digital workplace at home
communication devices
vax passport 🤡
Buy a book about hunting, gathering and farming I recommend.

7/ Today people learn coding using Jupyter notebooks. Good night I say. I hate it, but that’s where I ended too. Those people starting like this will never go down to low level or write a consistent piece of object oriented complex software.
8/ Today society has stopped valuing mathematics and intelligence as the most important skill for hiring. Instead even VC firms and startups are implementing the deadly intersectional equity cult. That will end in self destruction.
9/ The entire society is moving away from merit and skills towards the self destructive equity. Schools, politics, media, everywhere. That’s why we are unable to “solve”, understand the Covid crises. Stupidity is everywhere. We are going down. Inevitably. But it’s exciting too.
