a *lot of steps

• a lot of pioneering in the ’70s*
• right there in the late ’70s*
• Most people ended the ’70s* living like they did in the ’60s*
• a lot of invention in the ’80s*
• crystalized in the ’80s*
• We emerged from the ’80s*
• lot of evolution in the ’90s*
• a lot of revolution in the 2000s*
• a lot of stagnation in the 2010s*
• Now we arrive in the 2020s*
• In truth this began in the 2010s*
• the sinisterization of the ’20s*

But you got it right for “TRS-80s” & “August of ’91”!
