If you want an idea of -what- they are avoiding, LeoLabs operates a set of radars which track anything larger than 10cm in cross-section, and provides an awesome visualization here:<br>

Indeed, I read that. But the article does not explain why they think<br>

this trend will continue exponentially.<br>

Obviously it can't continue exponentially forever, because eventually<br>
