50yr old tech (mouse) still hangs around because it is effective. Whatever this Google slop is, will likely not replace mice. The mouse has been successful at passing the test of time. Most of Google's own hardware products don't last 1/20th of that time.

There's a reason chairs are still around. They are +2000 years old. Its still waiting to be replaced.

One should be extremely skeptical of claims of replacing tech that has been around for a very long time.
