This sounds more like your opinion. The EV car segment is the fastest growing market and is growing exponentially YOY. If people had no problem buying 10+ year old tech then the EV car market would not be growing. EVs are essentially a computer on wheels, so technology is only going to become an increasingly significant differentiator.
No, it's not really just my opinion. However, it may also not be publicly accessible fact, as it's mostly based on the data my team and I collected by order of third parties. Nevertheless, several particles of it can also be researched online.
When I say "most people don't really care about how old their car is tech-wise" I'm referring to countless interviews we conducted over decades with buyers of late-cycle/long-cycle models. It was surprising to me that, especially in higher segments and very often among buyers, people often don't care if the vehicle they buy actually had been developed >10 years ago and doesn't meet latest standards at all. Many don't know any spec details. Only recently, we did a benchmarking thing with SUVs and among GLE/GLE coupe/GLS users there was quite a substantial amount not showing any interest in new models but instead claiming they will buy final production predecessors. This was particularly striking as, in this case, the old model had a particularly long tech cycle and the old-new-delta is pretty massive.
Now, the E market is still immature and virtually nobody really knows what exactly will happen. You're right, the market is growing rapidly BUT still we're talking about rather small absolute numbers. AND: E customers are a rather special breed. Some collegues and I have tried to study and collect data on this community starting in 2012, some of us even went undercover

. Let's put it like this: E customers differ a lot across time and markets. Also, variance in technological knowledge is huge. There are about 1/3 average, low-key users, 1/3 real specialists but another third wisenheimers thinking that driving an e car qualifies them to explain the world to all those anti-Elon rednecks. The specialists know everything about their car, charging physics, battery chemistry but also about energy issues around their homes, etc. The others know what Elon said during his presentation or on Twitter. Since the specialists, at least in Europe, are often true pioneers, lots of them started dealing with the topic of electrification long before any mainstream trend emerged and were socialized with little plastic boxes in the late 70s/80s. The majority of those still mostly drive (again, in Europe) small BEVs such as Twizy, ZoE or i3. Long story short: those who might understand how avantgarde their vehicle's battery, plattform etc. are obviously don't care too much about pissing contest numbers and those who do often lack the technical expertise.
I'm aware there are exceptions to this. What is bothering me most is this: the number of so-called car experts who actually did not care about cars before Tesla hit the market and do not care (or even know anything) about cars that have been there before is growing at an insane pace. Those folks often make very bold claims and arrogantly void technological achievements 'old' OEMs made for them. Imo, those voices should not be the only ones to define what a modern car is or is not.
