What he's trying to say is that you're completely wrong. Tramiel killed Atari. Remember his terrible decisions that destroyed the most pioneering company in video gaming history?
"Game machines were dead"?!?! No, Tramiel decided that game machines were dead, and he was absolutely wrong. He froze the 7800 right when it was ready for market in 1984. He gutted Atari's arcade and home console divisions to focus on computers.
Then, after the success of the NES, he decided Atari needed to make a console again. But did he commission a new design? Nope, he brought back the 7800, slashing the specs from its 1983 design so that it was even further behind the NES and Master System. Another puzzling decision in the name of saving money.
In 1984, the 7800 had the best ports of the most popular arcade games ever made. In 1987, it was light years behind the NES and Super Mario Bros. Atari would never recover from Jack's decisions.
