I am concerned every ETF will rely on SPACE X which is going to likely be volatile. Much like Nvidia in Tech ETFs today. What do you think? Also 401K accounts- is this going to get pushed on everyone since the underwriters will need to sell it? I believe we should be able to choose ETFs and exempt stocks form out retirement target age accounts. I guess ETFs are inherently more transparent than target date and are appealing for that reason?
