If you pay with card there will be an electronic trace.

Our power problems today are far away from the theoretical limits you described.

But reversible computing is inevitable in quantum computers, so it's researched in that context.

A bit of survivorship bias in your question.

You are comparing the absolute best from 100 years ago with the average peer from today.

There were also far far fewer "researchers" back then.

Big software companies create and open source stuff which makes them more productive.

Why doesn't this dynamic work in hardware?

Wouldn't "valuing hardware" improve their competitiveness?

Neither has fusion research produced anything for us yet. Should we stop funding it?

> A reasoning and conscious machine would be just as or more moral than us. There is no rational argument for it to exterminate life.

We drove the mega-fauna into extinction without actually planning for that or desiring it.

Same thing today, where we are crowding out all the other animals and causing mass extinction, without desiring particularly to harm them.

You can use just ray.core to do multi process.

You can do whatever you want in the workers, I parse JSONs and write to sqlite files.

"Ray" can share python objects memory between processes. It's also much easier to use than multi processing.

The "ray" library makes running python code on multi core and clusters very easy.

Quality anti-aliasing is expensive.

So you want to allow the implementation to decide how much to spend on it depending on available compute, battery and so on.

Games targetting pre-Pentium PCs also used precomputed trig tables.

Pentium was fast enough that it didn't matter as much.

Just a few years later it was slower to read a trig precomputed table.

Criminal rights are a different thing.

There are tons of commercial rights EU citizens have which don't apply if you are an EU citizen living in US - for example warranty rights.

Not a credible threat. There would be millions of people in the streets if Facebook/Whatsapp/Google were blocked due to EU regulations.

90s apps used these Windows handle controls and it was not a performance problem. On computers 100 slower than today and with 1000 times less memory.

BTW, the current Windows Task Manager still shows the total HANDLE count on the CPU page.

They were not used in apps with complex UIs because native controls were hard to skin and didn't work very well when their size was very small (as complex UIs tend to need)

Pro cameras have a volume problem. Too few are sold.

Imagine if Intel only sold 10000 CPUs a year, but the fabs still cost billions of dollars. Do you still think you would have $500 CPUs?

Tensor cores massively accelerate matrix multiplication with no algorithmic breakthrough. Just by being smart about how you move/cache/reuse values, operations which are considered O(1).

There should be an O notation which takes into account everything - various kinds of memory latencies, speed of logic operations, .... Obviously we have wall clock or total energy used.

What if management was notified that the employee doesn't follow procedures yet did nothing?
