That describes literally anyone who's ever tried to make a difference. It's a poor excuse.
It's not an excuse at all. Clive Sinclair designed the ZX Spectrum which revolutionised the computing industry in the UK and opened computing up to the general public...then he did the Sinclair C5 which, honestly, sucks balls.
So do we laud him for the former or ridicule him for the latter? Bit of both I guess.
But any innovator's ideas will be a bit hit and miss. So if your point is "this is a stupid idea" then I basically agree, but I'm sure there are times in history when people were saying "this is a stupid idea" and the person did it anyway and it was a huge success. Such is the lot of an inventor.
Ah, yes, the peak of practical thought - claiming to have dumped rubbish into space because of reasons.
Well, I agree it's not the most practical thing. I think he did it partly as a publicity stunt, partly as a proof of concept, partly for the fun of it, because he
could. If I was a billionaire I might do some cool stuff like this.
But my point is he did do it and has a queue of people willing to take his money to launch stuff into orbit. So either he really can do that or he's somehow fooling people into thinking he can. Not entirely sure how he would fake a satellite, presumably the people paying him aren't just wanting to put cars in space, they surely want the satellites up there for some practical purpose and if they weren't operating as expected he'd be having to refund a lot of disgruntled customers.
