A question to compter hardware experts

[Syndrome]

It dawned upon me that the laptop I'm currently using is the one I have used for the longest. ASUS G55V purchased in 2013. In the past I used to update my hardware between every 3 and 5 years. This machine still works fine. I remember the first few PCs became unusable after about 4 years.

With the law of diminishing returns and Moore's Law slowing it appears there isn't a need to change hardware as often as in the past. Does it mean computers as we known them have reached there peak with new and significant changes will become more scarce?
