Is it still bad to use swap on a modern SSD?

I have the exact same SSD w/512 GB and Ubuntu 16.04 setup an GB SWAP partition on it. I see no problem because:

• with 8 GB RAM the swap is never used so no worry of shortening 10 year life span.
• I typically shelf laptops after two years and buy a new one.
• If I do get into Virtual Machines (VM’s) some day I’ll upgrade to 16 or 32 GB RAM as soon as I see SWAP being used.
• The only other option would be 1 TB HDD and I’d like to keep that as destructible storage space and not worry about it.
• The only downside is expensive real estate parking SWAP on most expensive SSD but Ubuntu only uses 16 GB and Windows 10 is only using 110 GB of 385 GB allocated.
• An advantage is if SWAP is ever used for massive memory leak then OOM-Killer (out of memory killer) will tell me 20 times faster I have a problem. This is because I believe our SSD’s are about 20 times faster than the average hard drive.

Monitoring Samsung Pro 960 M.2 NVMe Gen 3.0 x 4 SSD

First step is to install nvme-cli because it provides the most information:

sudo apt install nvme-cli

Next gather information available from SSD:

$ sudo nvme smart-log /dev/nvme0

The most important field is Percentage used which shows as 0%. This isn’t disk usage percent but life used percent. I’ve had this drive since October 2017 and now it’s May 2018. As soon as Percentage used hits 1% I can multiply the number of months I’ve owned it by 100 to find out when it will die. But they say the drive typically lives longer than that.
