I don't think that mostly people realize when they are buying tech and not an aquarium product. There are products that are made to last - lots of them... but most of them are not super techy. You can still get US, Italina, German and Japanese made aquarium products that will last a long time.
You can still get Askol block pumps, Iwaki, PanWorld, Eheim stuff, Tunze, T5 and MH lights... all that can last decades.
If you are buying tech, then some of that cost is for coolness, development, apps, etc. ...actually, most of it probably is. Have reasonable expectations.
