Car industry is going in the direction of manufacturer rebuild (remanufacture), so laptop industry should do the same. Instead of making unupgradeable garbage, manufacturers should offer upgrades.
I do recall a neighbour of mine saying "back when cars went rusty" to me a decade back, which surprised me. A lot. Apparently they don't now?
But modern cars, and many modern motorbikes, are sealed units which are not maintainable by the end-user. I dislike electronics like that.
For this reason, for years now, I have favoured very cheap smartphones. If I must have a sealed brick that I can't fix or upgrade, then I will have the cheapest one I can get that does what I need.
Luckily, there are very decent £/€ 125 smartphones now, from companies such as PPTV, iRulu and Umidigi, which are entirely usable and which I can replace every couple of years without pain.
For laptops, I just use decade+ old Thinkpads for now. They're fast enough for me and the keyboards are better than any modern thing.

I ask because I sort of went the opposite road, making sure I bought something that would last a long time.
Aside from screen resolution and the modern “anything” thinking we all have high resolution monitors my old 2015 MBP is still performing just fine despite its heavy usage.
In the same period I’ve gone through 5 or 6 work laptops that were certainly not top end.
I’m of course scared that the glory days of Apple died and my next mbp won’t live 10 years, but I hope so.
My 2015 MBP made it to the end of 2021 for me - when the fans started to have to run constantly and even still caused thermal throttling - when I had 2 Thunderbolt external displays attached (thus running the discrete GPU). I think it was an OS bug introduced in Catalina or Big Sur.
I even tore down my hardware and re-applied thermal compound and clean dup the heatsinks...no joy.
Running "pmset -g thermlog" while using it sealed the deal for me. I was only getting a fraction of the CPU power when running on two displays (and this is when the ambient room temp was 68-70F). I had a day when my AC conked out for a day and the room temp jumped to 76-78F and it was unusable.
I am really enjoying my 16" 2021. Didn't realize how much of a slouch my 2015 had been by comparison.
That being said, I still rock a mid-2012 MBP for light tasks when I just need a laptop and not a desktop replacement laptop.
I recently (end of last year) bought i7 versions of the T420 and T520, because for me they are the last generation of Thinkpads with good keyboards, and I hope they will last me for a while.
My phone? It varies but typically every 18 months - 2 years. Phones lead hard lives and don't last very long.
Current: Umidigi F2. Before that: 2nd hand iPhone 6S+. Before that: PPTV King 7. Before that: Blackberry Passport (used). Before that: iRulu Victory V3. All those in the same time period that 2 old Thinkpads have covered, and all were relatively cheap.
