Georgetown-Penang retains it's colonial founding and influence. It's more of a laid-back 'city-island' just a couple of hours drive from the troublesome southern Thai border. Not a wild ride brand like BKK or Pattaya.
How long it will remain peaceful nobody know but that is the same for anywhere.
I think the past problem was one based on ethnic background where there was a groundswell of violence from 'ethnic'-Malays against other ethnic groups...though most all were of the Muslim religious orientation.
That must have been a marvelous ride in 1980. I envy you.
(Were you with a farang lady at that time in your "late 20's" ?)
