Ironically their buying has placed bitcoin  above Tesla itself  in ^{terms of market capitalization.} . Generally speaking I see this as a good sign showing Bitcoin is on the verge of mainstream. Musk is proved  to be a powerful influencer as to crypto, so his decision to play with BTC will push it high. Is this good for poor people, probably not, because price of $50 000 and above would mean less people could afford to buy it.
