There was no replacement. It's just that the Intel driver folks at the time failed to properly implement core rendering and switched from one acceleration architecture to the other, each clearly superior to its predecessor except having a new unique set of bugs (sarcasm intended). Removing XAA killed hardware acceleration for 20 years of graphic cards, but that doesn't matter to people mostly paid by graphic card companies, since those older cards are obviously not generating revenue.

Thank you for proving my point. The most obvious danger is that a PV cell with micro inverter should be used on a circuit of its own, because it can prevent fuses from working properly. This is especially problematic in America due to the lower voltage. Let's say you have a 15 amp circuit and a 500W PV cell working at maximum capacity. If there are also consumers on the circuit, the wiring can be constantly overloaded by 30% without the fuse triggering. That's easily enough to create a fire hazard if the installation is even a bit shoddy.

AC circuit breakers and fuses in electrical panels exist to protect downstream wiring. They do so regardless of direction of current flow. If less current feeding an outlet is pulled in either direction a protection device need not trip. If more is pulled in either direction the protection device interrupts the circuit.

If current from PV feeds local loads thereby reducing current required to be pulled from wires feeding an outlet this would indeed allow loads to run on the circuit that would otherwise trip the protection device. This isn't a dangerous condition because the wires feeding the outlet are not being overloaded.

This faulty reasoning is exactly why it is dangerous. If you have a 15A fuse, wiring is rated for a bit less than that as permanent load. If you have a PV feed of 5A in the circuit, consumers can pull at least ~17A without triggering the fuse. That's enough to start damaging the wires over an hour or two.

The other major safety issue is that non-electricans have a history of ignoring installation rules and wanting to install more than one PV system. Once you have two micro inverters, the island detection can become unreliable

This is baseless nonsense. Systems with large numbers of micro inverters are common especially here in the US due to requirement for MLPE stemming from 80v per conductor limit of NEC 690. Anti-islanding is a universal feature of all such devices. The kits come with standard electrical wall outlets and are designed for normal people to plug into an available outlet and have millions of installs.

Not all anti-island detection implementation are the same. Some can detect parallel inverter, others can't. Chances are high that the cheaper the micro inverter (and therefore the home PV), the less likely it is to actually be able to detect this case. Especially when mixing different models, things become out of spec very fast and anti-island detection is essentially the feature that keeps the upstream RCD working.

Well, the complains we have here by petrol heads is that it doesn't help if the first world switches to EV, because the old gas suckers are just going to Asia and Africa. So if you operate under the assumption that Africa is buying only used cars, the timeline makes a lot more sense. There is no strong second hand market for EVs yet and it will take at least a decade for that to change.

Um... have you even tried vibe coding? You can one-shot a project in 20 minutes. I've done it numerous times - an old project I spent weeks writing specifications for, boom, done.

Have you even spent 5 seconds thinking about what you wrote here? If you need to spend weeks writing a specification and "vibe coding" it takes 20 minutes, it means you are either completely incompetent at writing specifications or your vibe-coded project simple doesn't do what you wrote in weeks. It's as simple as that.
