No, plastic was the mistake. That was the dangerous game, those plastic eating bacteria are one way to restore some of the natural order and hopefully at some point they'd run out of food.
Plastic is indispensable completely unlike electricity is indispensable.
Plastic is a huge pollutant, with breakdown stats that make you cry once you start thinking in terms of tons of absolutely indestructible stuff that makes it into our environment every day. Only a very small fraction of that stuff really needed to be made from plastic. Mostly it is just done because it is cheap and mechanically well understood. And because - tadaaaa - it lasts longer than most other materials. But the result is that the plastic invariably outlasts everything else, and it is super hard to recycle it efficiently unless it was expressly made to be recycled, which it rarely is.
Electricity is a highly fungible form of energy, in every way that matters unlike plastic and for which we do not have any alternatives that come close to having the same kind of properties for everyday use.
In many applications glass or treated paper was used prior to plastic and it usually worked well enough to give a reasonable service life. Lots - and I mean really lots - of applications where plastic is used today it could still be replaced by either paper, glass or sometimes wood. Using plastic for the remaining use cases would be fine by me. But plastics for 'economics' reasons is just a temporal form of externalization.
Plastic is indispensable just like electricity.
